Electrical corrosion protection – Prevent hydrogen sulphide corrosion in electrical and electronic equipment
Electrical corrosion protection - Prevent hydrogen sulphide corrosion in electrical and electronic equipment
Corrosion in its many forms, costs both private and public sectors hundreds of billions a year to repair or replace electrical, electronics, or avionic components because of failures caused by corrosion. Lost productivity and revenue caused by plant and equipment corrosion is a serious matter. While all metals corrode, due to a number of different factors, there is no simple or single solution to the overall corrosion problem. However there are some very cost effective and proven ways to prevent corrosion and failures caused by corrosion and thereby reducing or eliminating associated costs and increasing safety which should be foremost in the mind set of any preventative maintenance programme.
Electrical and electronic equipment and components that are used in adverse environments, e.g. the oil and gas industry, waste-water treatment plants and the pulp and paper industry, where corrosive gases such as hydrogen sulphide can be found, cause severe corrosion and the rapid deterioration of the electronic components and equipment including connectors and switches used in these and other work environments. Preventing hydrogen sulphide (H2S) corrosion in electrical and electronic equipment involves a combination of preventive measures and material selection. Here are some steps to mitigate H2S corrosion:
Protective Coatings:
An essential corrosion preventative measure is to apply coatings to vulnerable components. One such coating is Super CORR A advanced lubricant and corrosion inhibiting compound. It will help prevent H2S corrosion in electrical and electronic equipment, ensuring their longevity and reliability in environments where H2S exposure is a concern.
Material Selection:
Choose materials that are resistant to H2S corrosion. For example, stainless steel, nickel alloys, and certain plastics are less susceptible to corrosion by H2S compared to carbon steel.
Enclosures, Sealing and Ventilation:
Seal electrical and electronic equipment and cables in airtight enclosures to prevent H2S exposure. Ensure these enclosures are made from corrosion-resistant materials. Implement ventilation systems to reduce the concentration of H2S in the equipment’s environment.
Monitoring and maintenance::
Regularly monitor H2S levels in the environment where the equipment is installed. Install gas detectors to provide early warnings of increased H2S concentrations. Perform regular maintenance checks on equipment to detect any signs of corrosion. Replace any corroded components promptly.
Design Considerations:
Consider the design of the equipment and its surroundings to minimize the likelihood of H2S exposure. For example, elevating equipment above potential H2S sources can reduce corrosion risk.
Education and Training:
Provide education and training to personnel working with the equipment on the risks of H2S corrosion and the importance of preventive measures.
Emergency Response Plan:
Develop an emergency response plan in case of H2S exposure or equipment failure due to corrosion. This plan should include procedures for evacuating personnel and shutting down equipment safely.

The importance of corrosion protection for electric vehicles
The importance of corrosion protection for electric vehicles
Corrosion protection is as important for electronic vehicles (EVs) as it is in traditional petrol/gasoline powered vehicles. However, there are some unique factors to consider when it comes to avoiding corrosion problems in electric vehicles:
Battery Enclosure and Connections:
EVs have large, heavy battery packs that are typically enclosed in a protective housing. This enclosure and its connections can be particularly susceptible to corrosion, especially in regions with high humidity or exposure to road salt. Corrosion in the battery enclosure or on electrical connections can affect the performance and safety of the vehicle.
Charging Infrastructure:
Charging equipment, especially in public charging stations, can be exposed to the elements. The connectors, plugs, and wiring can corrode over time. This can lead to issues with charging reliability and safety concerns.
Cooling Systems:
Many EVs use liquid cooling systems to manage the temperature of the battery. The components in these systems, such as radiators and coolant lines, are vulnerable to corrosion. The resulting leaks or blockages in the cooling system can potentially lead to overheating and reduced battery life.
Underbody and Frame:
Just like traditional vehicles, EVs have underbody components such as the chassis, suspension, and brake components that are susceptible to corrosion, especially if the vehicle is driven in areas where roads are salted during winter. Corrosion can weaken the structural integrity of the vehicle.
Electrical Contacts and Connectors:
Electrical connectors and contacts throughout the vehicle can corrode, leading to issues with sensors, lights, and other electrical systems. This can affect overall performance and safety.
Material Longevity:
EVs often incorporate a variety of materials, including metals and alloys, in their construction. Corrosion can significantly reduce the lifespan of these materials, leading to premature failure of crucial components. Protecting against corrosion ensures the durability and reliability of the vehicle over time.
Safety Concerns:
Corrosion can compromise the structural integrity of a vehicle, posing safety risks for occupants. In an EV, where advanced technologies and high-voltage systems are prevalent, maintaining structural integrity becomes even more critical. Proper corrosion protection helps mitigate these concerns.
Performance and Efficiency:
Corrosion on electrical components, connectors, and conductive elements can hinder the performance and efficiency of an EV. For instance, corrosion on battery terminals may increase electrical resistance, leading to reduced energy transfer efficiency and overall performance. Ensuring corrosion-free connections is vital for maintaining optimal efficiency.
Cost Savings:
Corrosion-related damage can result in expensive repairs and replacements. By investing in effective corrosion protection measures, manufacturers and owners can avoid these costs, contributing to the overall economic viability of electric vehicles.
Environmental Impact:
EVs are often considered more environmentally friendly than traditional vehicles. However, if corrosion leads to premature scrapping of EVs or frequent replacement of components, it can undermine their environmental benefits. Proper corrosion protection helps maintain the longevity of EVs, reducing their overall environmental impact.
Maintaining Resale Value:
Corrosion damage can significantly reduce the resale value of a vehicle. As EVs become more common in the used car market, maintaining corrosion protection becomes essential for preserving the value of these vehicles over time.
Regulatory Compliance:
Different regions have regulations and standards regarding vehicle safety. Corrosion protection is often a requirement to meet these standards and ensure that EVs adhere to guidelines.
Aesthetic Considerations:
Corrosion can also affect the appearance of a vehicle. For EV manufacturers who emphasize design and aesthetics, ensuring that the vehicle maintains its visual appeal over time is crucial for customer satisfaction.
To mitigate and address corrosion issues in EVs, manufacturers take the various measures, including the use of corrosion-resistant materials, applying protective coatings and sealants to prevent moisture and salt exposure, regular maintenance and warranty coverage. It’s important for EV owners to follow manufacturer recommendations for maintenance and care, as well as be aware of their local environmental conditions. Proper care and maintenance can help reduce the risk of corrosion and ensure the longevity and safety of the vehicle. Additionally, addressing corrosion issues promptly can prevent them from becoming more serious and costly problems in the long run.
In summary, implementing corrosion protection measures for electronic vehicles should be based on specific circumstances and environmental conditions. Corrosion protection is fundamental for the long-term performance, safety, and sustainability of electric vehicles. It addresses not only technical and safety considerations but also contributes to the overall economic and environmental viability of EVs in the automotive market.

Corrosion protection for electrical control systems in Wastewater Treatment Plants
SuperCORR A protects electrical control systems against corrosive environments
Wastewater treatment plants are subject to corrosion and rust from a variety of causes, one of which is Hydrogen Sulphide gas, (H2S). Corrosion is an insidious and costly problem that causes just about every metal and metal alloy to fail over time. Metals in electrical and electronic control systems, components, connectors, and switches are of most concern.
Corrosion is found in almost all process industries including wastewater treatment plants, pulp and paper mills, fertilizer plants, and numerous other industries and is not going away. Establishing a ‘Preventative Maintenance Program’ that includes corrosion prevention makes it a problem that can be cost effectively dealt with.
One proven and positive way to reduce, if not prevent, corrosion altogether from causing electrical, electronic systems and component failures is by using an ultra-thin film water displacing lubricant material with corrosion inhibiting compound, SuperCORR A has all these properties.
A proprietary formulation packaged in aerosol cans it uses a non-flammable fast drying carrier solvent. The aerosol is supplied with a flexible tube applicator which allows the protective coating to be applied accurately even in difficult to get to components.
Removal of surface contamination from the metallic contact surfaces on switches and circuit breakers is essential to ensure fault free operation. The aerosol uses the unique
SuperCORR A formulation to lift and remove dust and soils from the metal contact surfaces. An inert compound that neither reduces nor increases the electrical conductivity. SuperCORR A also provides long term protection from corrosion and electrical arcing that can lead to shorts and subsequent circuit failures.
Testing SuperCORR A in corrosive environments
SuperCORR A (MIL-DTL-87177B (Revised MIL-L-87177A) Type 1 Grade B lubricant was subjected to extensive and vigorous Mixed Flowing Gas (MFG) testing at Battelle Laboratories under a U.S. Government contract.
Specifications ASTM B827 and ASTM B845 Class III MFG testing protocol were used. This included gases with high corrosion potentials including Hydrogen Sulphide (H2S), Nitrous Oxide(NO2), and Chlorine (Cl2).
ASTM B845 refers to techniques for mixed flowing gas (MFG) tests containing gases that are applied to evaluate devices containing electrical contacts such as slip rings, separable connectors, electromechanical relays or switch contacts. The MFG tests accelerate corrosive degradation processes. Connectors and contacts within closed electronic cabinets may be affected by an environment of different severity than the outside of these cabinets. ASTM B827 outlines procedures for conducting environmental tests involving exposures to controlled quantities of corrosive gas mixtures. Equipment and methods for gas, temperature, and humidity control for tests to be conducted in a reproducible manner are described.
Reproducibility is measured using control coupons whose corrosion films are evaluated by mass gain, coulometry, or by various electron and X-ray beam analysis techniques. Reproducibility can also be measured by in situ corrosion rate monitors using electrical resistance or mass/frequency change methods. Full copies of these tests can be made available on request.
Industrial applications
SuperCORR A has a proven performance record in protecting electrical components, systems, connectors and electronics. The coating will also prevent the ingress of moisture and other contaminants onto the connector surfaces. These initiate corrosions and cause intermittent component failure or a premature degradation of component performance.
The Battelle Laboratories studies provided data and related processing information validating the benefits of using SuperCORR A. to protect the electrical connectors of line replacement units (LRUs) used in military aircraft avionic applications.
The results of the laboratory and field-testing activities conducted in these studies confirm that SuperCORR A is an extremely effective coating to protect electronics, electrical components and systems including switches and connectors with no compromise of the integrity of the electrical component/system even in very corrosive environments.
As a result of testing on site at a number of private and public companies with the confirmatory work at Battelle Laboratories SuperCORR A is being used to reduce maintenance and repair costs in a range of different industrial applications – wastewater treatment plants, pulp and paper mills, automotive and heavy equipment industries and in the power production sector oil and gas and renewable energy and in both the aviation and maritime industries.

Critical cleaning of electronics and electrical components
ProSolv® 5408 new sustainable solvent for critical cleaning of electronics and electrical components
Solvents are used throughout industries where extremely high performance and safety critical cleaning levels are required including aerospace, military and defence, electronics, semiconductor manufacturing, optics, and industrial machining.
ProSolv 5408e is an innovative contemporary highly effective, versatile defluxer developed to not only remove rosin flux, no-clean flux, oil, grease and wax contaminants, but also to eliminate residual halide salts, ions and other polar and non-polar soils and contaminants that often cause component failures with tracking and other issues impacting performance.
Solvents based on conventional chlorinated hydrocarbons have delivered the high standards required for critical cleaning in the past. These chemicals had desirable properties which when combined gave a profile which was perfect for vapour/vapour liquid degreasing when combined with suitable equipment as industrial cleaning systems.
Non-flammable, consistent azeotropes, low viscosity, high liquid density, very low surface tension, and effective wetting enabling them to penetrate tight spaces for optimum cleaning performance. High KB values allows for cleaning a variety of light and heavy soils including particulates, ionic soils, oils, waxes, and greases these are no longer acceptable.
Evolving legislation for ecodevelopment demanded by governments worldwide demand inventive and original formulations for the use of solvents to continue to comply with the increasingly stringent legislation for protection of the environment and, even more importantly, safety of operators who maybe exposed to the products. In applications where formulated blends of halogenated solvents have been used very effectively in the past these are now required by changes in legislation to be phased out of use.
With their 25 years wealth of experience in this field as the inventors of the highly regarded n propyl bromide (nPB) based EnSolv range of precision cleaning solvents EnviroTech Europe created a contemporary new formulation based on recent research and developed a new solvent as a replacement for the “old” technology which has been found to perform just as effectively, but without the negative environmental, health and safety issues.

Medical Device Cleaning
ProSolv® 5408 high performance vapour degreasing solvent for medical device cleaning
Medical device cleaning
Critical cleaning is vital throughout the medical supply industry for safe, successful operations and procedures. Manufacturers of medical instruments, implants and other devices using metals, glass, ceramics and plastics must select a cleaning processes compatible with all these materials of construction, to remove oils and other contaminants from the manufacturing processes. The cleaning system must be proven to be safety critical and to leave no residues on the surfaces of the cleaned parts.
In this short article we discuss the benefits of condensation cleaning with ProSolv 5408e vapour degreasing solvent for medical device cleaning compared to water-based cleaning.
Water based cleaning options
Formulations for water based cleaners use combinations of surfactants to reduce the very high surface tension of water to allow penetration of the cleaning solution into minutes holes and very fine mechanical clearances. The solutions must solubilise oils, greases, cutting fluids, grinding and buffing compounds and remove particulate soils. Biocides are also present in these formulations to ensure no bioburden is carried over from the cleaning process.
After cleaning residues of chemicals must be removed or they may be a source of corrosion when the devices are in use. Multiple rinses in hot and cold de-ionised water using agitation of baskets or carriers or ultrasound to dilute and displace the cleaning liquids retained in minute holes, cavities and trapped between close tolerance metal surfaces.
Continuous production of high-quality deionised rinse water is extremely expensive, but the drying process is even more costly and environmentally challenging. Multiple cleaning and rinse tanks and drying ovens or tunnels need a lot of space and energy. Further controlled conditions are needed to cool parts after drying to prevent condensation of moisture, which can be growth media for bacteria, on the critically clean surfaces, before packing in sterile bags and containers for storage or shipping.
High output water based cleaning equipment can use conveyorised high pressure targeted spray tunnels for automated high-volume production with integrated “blow off” drying and conditioning tunnels.
For smaller scale operations systems are available using baskets in single cell dishwasher type equipment or open tanks. The latter can use manual or automated handling to progress baskets through the cleaning cycle using similar aqueous based chemical formulations with multiple deionised water rinses and a separate drying oven. These systems can process several baskets or carriers at a time so are only suitable for small batch production. In either case long process times will determine the size and complexity of installations.
Compare the complications of water-based processing to the simplicity and speed of vapour degreasing using ProSolv® 5408e solvents
Vapour degreasing or more properly condensation cleaning, is a proven process where a non-flammable halogenated solvent, safe for people and the environment is heated in the sump of a tank. Boiling solvent produces a dense vapour which is contained by condensation coils around the inner surfaces at the top of the tank. Solvent condensed on the coils is returned to the sump for reuse in a closed cycle.
Parts to be cleaned at ambient temperature are immersed in the vapour which condenses as solvent on the surfaces of the devices or parts in a continuous stream of perfectly clean solvent until the surfaces reaches vapour temperature when condensation ceases. Vapour degreasing uses only one tank with one liquid. Parts are cleaned, rinsed and dry in 3 to 5 minutes with parts hand hot ready for further processing, storage or packing into sterile packs for shipping.
ProSolv 5408e solvents were developed to provide superior critical cleaning performance for manufacturers of medical devices and equipment. The solvent is stable when used for vapour degreasing or cold dip cleaning and compatible with metals, including titanium, ceramics, glass and most plastics used in producing orthopaedic implants, dental, ophthalmic and surgical tools, lenses etc. ProSolv 5408e is a cost effective and sustainable solution to remove polar and non-polar soils and other contaminants and sets the standard for removal of machining and cutting oils, coolants, greases, grinding, buffing and polishing compounds, while leaving no residue.
Vapour degreasing and dip cleaning with ProSolv 5408e is a very effective steriliser of microbial contaminants. Exposing the microorganisms, which have cell walls made up of organic materials including lipids (Fats), to a powerful solvent is a very efficient disruptor of the cell walls. Once compromised the organism’s inner workings lose this protection and the organism dies reducing the bioburden.
ProSolv 5408e is also an excellent solvent carrier for organic or synthetic medical lubricant. This application for coating needles, cannulas and instruments needs consistent quality and evaporation rate to produce, comfortable, pain free insertion for patients.
In many medical applications oxygen and gas supply systems are needed and cleaning at installation and when extensions of pipework and fittings are added is vital for safety. ProSolv 5408e removes oil and organics leaving residue free, dry surfaces to standards approved by gas supply companies, and is compatible with all metals.
Clearly solvent cleaning and vapour degreasing with ProSolv 5408e is a better choice than water cleaning. Faster throughput, lower costs and sustainability to meet the unique challenges in achieving the high standards demanded for medical device manufacturing.
ProSolv 5408e is manufactured in UK with excellent customer service, technical support and training from qualified distributors throughout Europe.

SuperCORR A protection for USB contacts
SuperCORR A protects and lubricates contacts on the new Charge / Sync Cable from Lifedge
SuperCORR A lubricant and protective coating widely used by the military, electronics and aerospace industries for critical applications is used to protect contacts on the Lifedge lightning connector to USB cable to offer the protection needed in extreme conditions.
SuperCORR A deposits a dry protective film with excellent corrosion protection and lubricant properties plus the added advantage of a hydrophobic surface rejecting water that ensures the easiest and best connection for the very close spaced connectors.
Lifedge is the world’s first 100% waterproof, rugged Lightning to USB cable for charging and mobile connections whatever the weather or conditions. Developed for use in all outdoor activities including sailing, hiking, military, naval, surveying or other challenging uses. With an ultra-durable outer coating that will never fray and double-moulded, super-tough plugs, charging, downloading and data transfer is improved even in the most extreme and difficult conditions.
During the design of this new cable an extensive test programme, by Scanstrut, manufacturer of the Lifedge cable, was carried out to ensure the contacts were protected from corrosion in the salty and hostile environments in which the Lifedge connectors are used.
SuperCORR A dry lubricant widely used for critical applications in military, electronics and avionics industries proved to offer the protection needed. SuperCORR A prevents or delays corrosion and possible failures.
Testing by a major electronics connector manufacturer recognized that SuperCORR A is a lubricant formulated with corrosion preventive compounds, and as is the case with all “lubricants” will be worn off over time. SuperCORR A was tested to see what the “life” of the lubricant was in a “rub test”. The typical test is 20,000 cycles, i.e. unplug/plug in is one cycle. The test results demonstrated that after 20,000 cycles there were no failures. It was decided to take it one more step and run the same tests for 200,000 cycles. The results again showed no indications of galling or scoring on the USB connectors which looked and performed as good as new.
The extensive testing during the design of the Lifedge connectors validated the original tests and confirmed SuperCORR A will ensure the customer has the most reliable and easy to use connector, in often demanding circumstances. The robust Lightning and USB metal connectors are coated with SuperCORR A patented anticorrosion treatment for complete protection against the elements, whilst an integrated O-ring ensures IP66 waterproofing when charging with the Lifedge iPhone case. The cable is also compatible with protective cases from other leading manufacturers. Officially approved by Apple for use with iPhone, iPad and iPods SuperCORR A helps to bring new freedom and reliability with the Lifedge Ultimate Charge/ Sync Cable.
SuperCORR A is available as an aerosol spray and in bulk containers for brush and dip coating.

SuperCORR A Corrosion Protection Spray
Dry lubricant and corrosion protection spray reduces production downtime on industrial automation systems
Improving manufacturing productivity needs increasing numbers of robots, handling and positioning systems and conveyors which in factory environments need both scheduled and emergency maintenance plans to ensure continuous reliability. Failure of any part of the system will result in downtime and seriously disrupt production.
SuperCORR A from EnviroTech Europe is an innovative thin film dry lubricant spray with corrosion protective properties which does not attract dust or dirt, is stable and coats surfaces with an ultra-thin self healing, lubricant film unaffected by water or solvents and resistant to harsh corrosive atmospheres and high temperatures.
A recent case affected some clients of specialist cleaning equipment manufacturer C&C Hydrosonics a division of U.S giant Crest Ultrasonics to solve a problem occurring on x-y axis linear tracks on the Transystem automatic handling system fitted to enclosed multi tank cleaning systems both aqueous and solvent based.
Transystem automatic handling systems are programmable to automatically process baskets or jigs through liquid immersion cleaning cycles, transferring between the tanks, lowering and raising work between the tanks of cleaning liquids. The motorised carriages use nylon wheels running on case hardened mild steel tracks which can corrode during immersion and in the harsh humid atmospheres within the machine canopies.
Corrosion prevents smooth running with wheels seizing and binding on the tracks. Vibration can then cause components to be shaken from jigs or in extreme cases the carriage will stall requiring intervention by maintenance engineers to physically remove surface corrosion and re-lubricate tracks with oil. This is only a temporary measure as the oil is quickly removed by the solvents or water-based cleaning solutions with corrosion reoccurring in a short time.
Extensive trials over a six-month period with both water and solvent based systems demonstrated that SuperCORR A offered a simple solution to the problem with no corrosion of tracks or seizures during the trial period. Previously seizures needing attention occurred every few weeks now an aerosol spray of SuperCORR A is used only during normal service visits and is used as the routine lubricant during manufacture of the handling system.
Lee Casey, Managing Director of C&C Hydrosonics is delighted with the cost savings on reduced service and maintenance calls using SuperCORR A and that the inconvenience for users of the Transystem equipment has been eliminated. Use of SuperCORR A is recommended on all Crest handling systems worldwide.
Reduce maintenance costs and protect automation equipment with SuperCORR A, now available from EnviroTech Europe Ltd and distributors worldwide.

Aquus CL-One Concentrated Water Based Cleaner
Concentrated water based cleaner for all applications in manufacturing, engineering and general maintenance.
Aquus CL-One cleaner is a new formulation designed to deal with all cleaning applications encountered in manufacturing and engineering. It reduces time and costs by removing the need for multiple cleaning products usually needed to deal with the challenges presented by the wide range of soils, oils and other contaminants which need to be removed. Safe for the environment and users, contains no solvents and is biodegradable within 30 days. Typical applications in industry are discussed below but many more will be experienced in day-to-day operations. With only one product for all cleaning applications incorrect selection or dangerous uses can be avoided.
Concentrated Aquus CL-One chemistry is activated by water, varying concentration levels allows the most economical solution to be chosen for specific applications from parts cleaning to surface preparations for finishing or heavier soiling on process machines all from one product. Some of the hundreds of applications are discussed below.
PARTS AND COMPONENT CLEANING
Ideally suited for cleaning protective coatings, grease and soils from new or used parts. Aquus CL-One can be used in parts washing equipment or dipping tanks without modifications and leaves no residue after drying. Oil and grease separate from the water and coalesces on the surface of the cleaning solution which can then be skimmed off for recovery and recycling. Precipitated solids free of hydrocarbons can be removed by settlement or in filtration systems. The cleaning solution can be reused continuously within its chemical parameters for efficient and economical use.
GENERAL CLEANING
Aquus CL-One is remarkably efficient removing oils, greases, and accompanying dirt from most surfaces. It can be applied by wiping surfaces, mopping or in rotary floor cleaning machines, low or high-pressure spray. Aquus CL-One is also an effective cleaner in industrial kitchens removing grease and baked on deposits on internal surfaces of ovens and trays. For maintenance of machines, engines etc oil and grease is easily removed pre and post-assembly making inspection and repair easier, quicker and cheaper by returning equipment to use.
PREPARATION FOR PAINTING OR POWDER COATING
Aquus CL-One is an excellent choice for cleaning mild steel and ferrous metal parts which are not painted immediately. Process oils and grease on the parts protect the surfaces from changes in humidity but once removed flash rusting can occur while drying. Aquus CL-One prevents this leaving an invisible barrier on the metal surfaces providing extended corrosion protection during storage, fabrication or assembly before finishing. The barrier film can be painted over without additional rinsing and without affecting adhesion of paint or powder coatings. Various cleaning systems can be used, including hand wiping, dip tanks and pressure washing.

Corrosion control problems
Corrosion control is a serious problem for industry and governments worldwide.
Most people associate corrosion with rust, which only happens in things made of ferrous metals such as steel girders, ships, iron pipes, steel reinforcement rods, and steel tanks and is the reason metals deteriorate and fail.
Ferrous and non-ferrous metals corrode on contact with both fresh and salt water as well as water vapor. They will also corrode when they come in contact with chemicals, liquid acids as well as acidic vapors, salts and bases, and bacteria.
Read our article “Corrosion Control Solutions – A Solution To A Costly Problem” for more information about the enormity of the costs involved in failing to prevent corrosion.

Replacements for nPB
Envirotech Europe introduce low cost “drop in” replacements for nPB (n-propyl bromide) vapour degreasing solvents.
Bad news for your business. Coronavirus, Brexit, redundancies, social distancing reduced cash flow.
If that’s not enough and you are using nPB solvent that’s another problem to worry about as its use for vapour degreasing has been banned by the EU since July. Don’t panic it’s not too late to change and comply, as we have “drop in” replacements for nPB which are guaranteed to give the same results at no increase in your costs of usage. It is late but we can give you the information to easily make the change in a day without fuss.
You have questions – of course:
How can it be so simple?
The EnSolv range of stabilised nPB based vapour degreasing solvents has been the market leader in this field worldwide for many years. EnviroTech Europe, the manufacturers, know this product inside out with hundreds of satisfied users. We have been fighting the EU authorities for 20 years regarding classification, but with limited resources and the corporate giants with money to lose as EnSolv gained more and more of the market. Money talks so the Commission ignored the evidence and banned nPB for use as a vapour degreasing solvent with the sunset date in July 2020. If you are interested in the history, it is all explained in detail on our website.
With our extensive knowledge of user needs EnviroTech Europe, during the intervening years, have developed new compliant solvent formulations which are simple “drop-in” replacements.
No new equipment needed, guaranteed results and no extra costs to worry about.
We can’t guarantee that more changes will not happen in the future, but you will then have time to evaluate whether the new generation of wonder products which reduce global warming a smidgeon is worth the enormously increased costs.
Talk to us about whether EnSolv CC-A or ProSolv will be the best choice for your application. Advice, literature, changeover instructions are all available to make the change quickly, easily and at no extra cost of usage.
