Cleaning solvent for vapour degreasing in the aerospace industries

ProSolv® 5408 sustainable, economical cleaning solvent for vapour degreasing in the aerospace industries

cleaning solvent

The aircraft and aerospace component manufacturing industries face many critical cleaning applications during manufacturing processes and for finishing where surfaces need to be completely degreased leaving no residues. Although aqueous cleaning would seem to be the method of choice for environmental reasons with new advancements in cleaning solvent chemistry this is often not the case. Vapour degreasing is the most effective process, economical in use with lower energy uses, one tank needing less floor space than multi tank water-based systems and safe for users.

ProSolv 5408e has been developed to be used in place of the traditional chlorinated hydrocarbon solvents, trichloroethylene and perchloroethylene and those based on n-propyl bromide (nPb) which have been phased out for use as vapour degreasing solvents in the EU. The ProSolv 5408e advanced formulation, based on sustainable solvents, has been extensively tested with oils, soils greases and other contaminants from the manufacturing process and with is high KB value all these materials are easily removed to comply with aircraft standards for cleaning and degreasing to the highest levels. No titanium surface cracking or deleterious effects on other metals or composites commonly used for aircraft and aerospace component manufacture have been identified.

The innovative ProSolv 5408e formulation produced by Envirotech Europe ticks all the boxes with the perfect profile for vapour degreasing Soft on the environment with near zero ozone depletion potential (ODP) and very low global warming potential (GWP) its lower boiling point at 48C minimises energy requirements giving reduced process times for greater throughput and comfortably handled critically cleaned parts. The incredibly low surface tension guarantees penetration into micron sized through and blind holes and between close contact surfaces.

Stable in use ProSolv 5408eis safe for users with a high 8hr occupational exposure level of 220ppm. The solvent needs no additives or stabilisers and requires no testing. Sustainable, safe and secure for future use as your forever solvent.


CRITICAL CLEANING FOR THE AIRCRAFT INDUSTRY
A few examples of the many uses are discussed below, our technical service engineers can offer information and advice on critical cleaning in the multitude of other applications experienced in the precision engineering industries.

BONDING OF HONEYCOMB SECTIONS FOR COMPOSITES
An instance of critical cleaning is removal of all contamination from aluminium honeycomb prior to epoxy resin bonding of the formed aluminium skin to produce lightweight high tensile structures for applications such as leading edges on aircraft wings and wind turbine blades.  This is an extremely demanding application, as any residues will prevent the adhesion of the adhesives leading to delamination with potentially disastrous effects.

Due to the high standards of cleaning which are required this process is usually carried out by vapour/liquid degreasing with the traditional chlorinated solvents however due to the increasingly stringent controls on these materials ProSolv 5408e which is fully tested to aircraft industry standards and with its greatly improved environmental and user profile is now increasingly used as the sustainable and safer replacement.

CLEANING FOR CRACK AND FAULT TESTING OF WELDS AND CASTINGS
Another common use in the aircraft industry is in the cleaning of castings and metal fabrications before the use of NDT crack detection fluids. Removal of all surface contamination from manufacturing processes is vital to expose faults. Vapour degreasing and vapour liquid cleaning with ultrasonics is a favoured method due to the excellent solubility of oils and greases and other soils using one tank with very fast processing and parts emerging completely clean and dry. Crack and fault detection in casting and welds is also important in other industries such as railways, automotive engines, and turbines where castings or critical welded fabrications are used. This is particularly relevant as part of the maintenance procedure for refurbishment of aircraft landing gear where surfaces can be heavily contaminated by hard to remove hydraulic oils, rubber and cement dust and grease.

Because this application needs completely degreased, residue free and dry surfaces, the use of slow drying cleaners such as hydrocarbons or water-based cleaners may cause problems as the cracks need to be dry to allow penetration of the detection fluids. Vapour degreasing is the most effective cleaning system for all NDT applications as parts emerge dry from the cleaning process. ProSolv 5408e conforms to SaE-AMS2664 and E1417 99-1/7-1-1 solvent precleaning standard for Penetrant testing in aerospace applications.


CRITICAL CLEANING OF OXYGEN AND GAS SYSTEMS
Critical cleaning of oxygen lines and tanks where no organic residues can be tolerated is another ideal use for this new sustainable cleaning solution. ProSolv 5408e conforms to CGA, ELIGA and Compressed Gas Association standards for this application. We have a series of guides to using ProSolv 5408e for component cleaning to Oxygen standards and recommended cleaning methods involved, available on request.

ProSolv 5408e is produced to consistent quality standards worldwide and is available through a network of experienced and qualified suppliers.

Corrosion protection for electrical control systems in Wastewater Treatment Plants

SuperCORR A protects electrical control systems against corrosive environments

Protect Electrical Control Systems

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

critical cleaning of electronic 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.

ProSolv Benefits

Listed above are just some of the benefits from using ProSolv 5408e, your forever sustainable solvent for cleaning and defluxing in the electronics and electrical components industry and an economical and efficient “drop in “for vapour / vapour liquid cleaning systems using legacy solvents. EnviroTech experts with many years of experience are available to guide you through changeover procedures or to advise on equipment.

Medical Device Cleaning

ProSolv® 5408 high performance vapour degreasing solvent for medical device cleaning

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.

SuperCORR A protection for USB contacts

protect 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

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.

ProSolv®5408e cleaning solvent for flushing refrigeration pipeline systems

cleaning solvent for flushing refrigeration pipeline systems

Cleaning solvent for flushing refrigeration pipeline systems

Concerns connected with the challenging environmental profile of traditional refrigerant gases have led to changes in legislation which are a driving factor in phase-outs and bans on the use of some gases to remove the older materials typically with high ozone depletion (ODP) and global warming potential (GWP).  Systems can be replaced or refurbished with new models using compressors able to use more sustainable and acceptable gases. The evolving trend to newer refrigerants continues as the chemistries develop. The refrigerant R-22, which itself was an improvement over earlier refrigerants, is phased out and replaced with R-410a and other alternatives based on HFOs are being marketed.

Retrofitting of current refrigeration systems to accommodate the new developments is not straightforward as most refrigerant gases are not cross-compatible, so the necessity to completely remove all traces of the older versions from the system, including refrigerant lines is essential.

Of course, where possible it’s best simply to replace existing lines with new ones. However, it’s not always possible to do this cost-effectively, especially when the old piping runs under floors or through walls. In such cases thoroughly flushing existing pipework is especially important because even tiny traces of impurities left in the lines can damage new equipment and lead to compressor failure.

THE PERFECT SOLVENT FOR FLUSH CLEANING REFRIGERATION PIPEWORK

Your first step to proper pipework flushing is to select the right solvent. The solvent you choose must be highly effective at dissolving oil grease and other contaminants, to ensure that all residue is removed from the pipes and must be sustainable, environmentally friendly and comply with current legislation.

ProSolv 5408e is the ideal solution to this problem with a profile of properties and advantages making it perfect as your solvent of choice for refrigerant pipeline flushing.

No flash point Non flammable liquid.
High specific gravity gives a high soil suspension loading.
High solvency strength with a KB value of 98.
Powerful cleaning agent that can flush lines fast, dissolving oil and grease releasing soils from the inner surfaces of pipelines and fittings
Volatile for fast evaporation. Removing ALL solvent from the pipework after flushing is vital, very volatile so evaporates fast.
Environmentally responsible. ProSolv 5408e is sustainable and kind to the environment with very low global warming potential, zero ozone depleting potential (ODP).
Safe for operators when user conditions are followed.
Economical as it is easily distilled for reuse. No testing or stabilisation required.

PROCEDURE FOR FLUSH CLEANING REFRIGERANT PIPELINES WITH ProSolv®5408e

Of course, simply replacing old piping is the only way to be 100 percent sure that your lines are clean. But in retrofit situations where complete replacement is not possible, flushing the lines with ProSolv 5408e solvent is the best alternative solution for the protection and long working life of your refrigeration system upgrade.

1 – Remove any obstacles. Any equipment and components such as valve, filters and expansion valves that might obstruct the line should be removed prior to the purge.
2 – Pre-flush. This will dislodge any loose debris from the sides of the lines enabling more effective use of the solvent, oil free air or nitrogen at 120 psi is recommended. It’s also good practice to oscillate the pressure to encourage dislodging of debris.
3 – Preparing the pipework. Reducing the length of piping can be more effective due to the pressure loss in long lengths. Section the operation into 15 metre lengths by cutting pipes where necessary. One end of the pipe must be fitted with a connector for the pipe to the nitrogen supply while the exit needs a restrictor valve to allow variable pressures to shock loose particles from internal walls.
IMPORTANT – Flushing with solvent. Refer to ProSolv 5408e Safety Data Sheets for advice on operator protection using solvents.
4 – Safe working. Full PPE with suitable eye protection goggles and gloves must be worn. Solvent fumes are heavier than air and exposure levels can easily be reached working in pits or enclosed spaces. Always institute a ‘buddy system’ and use air fed face masks with attached line.
5 – Delivering solvent. Use a drum pump electric or hand operated with a flexible tube connection for delivering the solvent to the open end of the pipe or tubing to flush the internal surfaces. Using a fresh drum of ProSolv®5408e connect drum pump and the delivery tube to the end of pipe/tube to be cleaned using a pre-fitted screwed or compression fitting.
6 – Drainage and Testing. The drainage end of the pipe or tube should be fitted with a flexible tube into a tank or drain sump allowing samples to be taken in a glass bottle or tube at regular intervals to be sure when no particles or soils are being expelled. The colour of the solvent will change as oil and soluble contaminants are removed and flushing must continue until the flow is totally clear and water white.
7 – Post-flush. ProSolv 5408e solvent is volatile so will dry completely using an oil free airline or nitrogen supply connected to the end of the cleaned pipe/tubing.
8 – A wipe of the pipe/tubing surface at the inlet and outlet using solvent saturated lint free cloth completes the cleaning. If not connected immediately to other parts of the system enclose both ends of cleaned item to prevent recontamination.

Used ProSolv 5408e should not be reused for flushing but can be recovered for reuse by a simple distillation process. Removal from site should use licensed disposal companies.
