SuperCORR A – Advanced corrosion protection for automation and engineering industries

Corrosion is serious problem for industry and governments worldwide

Corrosion, in its many forms, costs both private and public sectors vast amounts of money to repair or replace mechanical, electrical and electronics components. While all metals corrode, due to various reasons, 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, thereby reducing or eliminating associated costs and increasing safety, which should be of foremost importance in the mind set of any preventative maintenance programme manager.

Corrosion is an increasingly serious and costly problem that can lead to equipment failures which range from being an annoyance to being catastrophic. Failures caused by corrosion could and do lead to a direct failure of a component which could affect the entire system and can not only be very expensive in terms of down time to repair or replace but can also prove to be very costly in loss of productivity, and possibly the loss of human life.

The financial cost of corrosion accounts for between 3% to 6% of a country’s GNP [1] and a 2016 study by NACE International concluded that the annual global cost of corrosion amounts to USD 2.5 trillion [2]. These costs increase each year.

A vast amount of the annual cost of corrosion can be saved by using corrosion inhibitor products such as Super CORR A which was specifically designed to lubricate and prevent corrosion in electrical fittings and connectors, electrical harness assemblies and connectors, electrical and electronic switches, close tolerance and dissimilar metal components, lighting connectors and sockets. It is a non-flammable “self-healing” ultra-thin film lubricant with a proprietary corrosion preventive compound that will not harden or crack. is not a wax or oil-based product and is formulated without sulphates, chlorides or halogens.

Super CORR A is a unique and proprietary formulation with long-lasting, anti-corrosion inhibitors providing a superior lubrication coefficient and protection against moisture, wear, general and fretting corrosion, static electricity, corona, and other electro migration problems. The non-flammable film is only 7 microns (0.007mm) in thickness, is not a wax or oil-based product and is formulated without sulphates, chlorides, petroleum-based material, or halogens, to meet the EU RoHS directive.

Manufactured and supplied by EnviroTech Europe Ltd, it is unexcelled in preventing failures of electrical systems and electronic equipment caused by corrosion as well as preventing the corrosion of metal components surfaces. Use Super CORR A to protect connectors, electrical systems and switches and mechanical controls during servicing. It’s ability to displace water from exposed contacts can ensure reliable operation in extreme conditions, all from one small aerosol can.

SuperCORR A - Corrosion Inhibitor

CASE STUDIES

Prevent hydrogen sulphide corrosion in electrical and electronic equipment

Electrical and electronic equipment used in adverse work environments (e.g., the oil and gas, water treatment, pulp and paper industries) where corrosive gases such as hydrogen sulphide are found, can be particularly vulnerable to corrosion and lead to the rapid deterioration of the electronic components including mechanical controls, connectors and switches. Super CORR A inhibits corrosion caused by exposure to both fresh and salt water moisture as well as the corrosive vapours from Sulphur dioxide (SO2), Nitrogen dioxide (NO2), Hydrogen Sulphide (H2S), Ammonia (NH3), and Chlorine (CL12) based gases found in waste water and sewer treatment plants, pulp and paper mills and plants, chemical and petroleum plants, maritime industry, aircraft/airline industry, military equipment including ships, aircraft, and rolling stock, auto industry, farming and agriculture industry, and the list goes on.

HFC-227ea gaseous fire suppression for electronic equipment.

When activated in a fire situation HFC-227ea will decompose to produce Hydrogen Fluoride. This is a real and ongoing concern. Why? Because Hydrogen Fluoride causes major corrosion problems for electronics and connectors. You may save your equipment but for how long?

To prevent corrosion caused by Hydrogen Fluoride, as well as other chemicals, acids, salts, and water which can be deposited during the activation of fire suppression systems or rapid humidity changes, all the electrical and electronic hardware, boards and connectors should be sprayed or coated with Super CORR A. It will protect and prevent damage to the electronics or avionics caused by exposure to the Hydrogen Fluoride produced as a by-product during the fire.

Fretting corrosion on gas turbine connectors

LP Gas Turbines are used throughout the world by extraction industries and manufacturing plants in remote and hostile locations for essential power production. Dusty and wet environments in deserts, mines, grinding mills, pulp and paper mills and on land or sea drilling rigs for gas and oil production. Turbines powering aircraft services while stationary connect and disconnect many times a day in extreme conditions. These applications and locations test connector sealing continuously allowing dust or water to penetrate. This with the flexing of the connecting cables allows sufficient movement between the metal surfaces of the connecting pins to produce fretting corrosion which reduces, interrupts or produces failures in supply. Regular maintenance of electrical connectors is essential to be certain of uninterrupted supply.

Containing extremely long-lasting, proprietary anti-corrosive inhibitors Super CORR A provides a superior lubrication coefficient and protects components against moisture, wear, general and fretting corrosion, surface static electricity, corona, and other electromigration problems.

Avionic corrosion protection

Super CORR A extends the working life of avionic harness assemblies, electrical systems and other critical items in aircraft maintenance by preventing the deterioration and/or failure caused by corrosion and can significantly reduce downtime, operating and maintenance costs as well as enhance safety. It has as undergone extensive testing by Battelle Labs as well as the U.S. Air Force and meets MIL-DTL-87177B (revised MIL-L-87177A) specification.

Super CORR A is used by NATO (NATO NSN 8030-99-226-6966) to protect avionic electrical switches, sockets, connectors and components from corrosion in both the military and civilian aircraft. It is the global industry standard for electrical corrosion protection, for in service maintenance by both military and commercial aircraft major repair and overhaul (MRO) facilities.

Sea Spray exposure

Most people associate corrosion control 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 saltwater as well as water vapour. They will also corrode when they come into contact with chemicals, liquid acids as well as acidic vapours, salts and bases, and bacteria.
The U.S. Navy selected Super CORR A after exhaustive testing using American Society for Testing and Materials (ASTM) Standard B117- Standard Practice for Operating Salt Spray Apparatus.

Super CORR A out-performed 11 other products in comparative testing to identify a better product to protect and lubricate the flap tracks and screw jacks on the aircraft. Super CORR A was evaluated against competitive products under the Federal Test Method Standard #791B, using a five percent Salt Spray Corrosion Test.

Mild Steel panel exposed to sea spray
control switch corrosion

The use of Super CORR A in regular maintenance procedures can bring financial savings in reduced maintenance and replacement costs, and more importantly, greater safety.

Maintenance of contacts on portable gas generators

A leading manufacturer of connectors tested Super CORR A 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 connectors at all. The connector looked and tested as good as new. This test was run under clean conditions in a laboratory but demonstrates the effectiveness of the protective lubricant in Super CORR A.

Unpainted metal in highly corrosive environments

Tests demonstrate the amazing properties of Super CORR A corrosion protection spray to protect unpainted metal surfaces from corrosion. These are photographs of 3 unpainted copper components that were exposed for a month next to the “digester” at a Pulp and Paper Mill.

The main atmospheric corrosion was from hydrogen sulphide (H2S) gas, produced during the cellulose digestion process, which combines with the atmospheric humidity to form a mild acid. Any unpainted or untreated metal surface, copper, brass, mild steel or alloys of zinc and manganese or magnesium will be corroded by this acid when it condenses on the metal surfaces.

metal corrosion

Tests demonstrate the amazing properties of Super CORR A to protect unpainted surfaces from acidic corrosion. As an example, copper and aluminium condensers on water coolers usually last about a month in the acidic environment of pulp production facilities because the corrosive atmosphere around the plant corrodes the metal surfaces on fins and connections.

Super CORR A has been also used to protect contacts on the Lifedge lightning connector to USB cable to offer the protection needed in extreme conditions. During the design of this new cable an extensive test programme was carried out by Scanstrut to ensure the contacts were protected from corrosion in the salty and hostile environments in which the connectors are used.

CONCLUSION

It is clear the use of Super CORR A for corrosion control can not only bring financial savings in reduced maintenance and replacement costs but more importantly greater safety. It is much simpler and a lot less costly to prevent corrosion than to repair or replace the damaged equipment or component that failed because of corrosion. As you have seen The photographs show the effects of protecting metal surfaces and components in extreme condition with Super CORR A.

Super CORR A is packaged in aerosol cans making access to component parts easy for engineering crews in difficult locations and conditions. Unpainted mild steel will not rust on exterior surfaces directly exposed to sea water environments for at least 6 months, protecting electrical connectors, switches, chains, drive shafts from corrosion while maintaining lubrication on moving surfaces.

Vapour Degreasing Solvents – Innovation driven by legislation

Vapour degreasing Solvents

Vapour degreasing Solvents – Innovation driven by legislation

Vapour degreasing is the simplest but most effective industrial solvent cleaning process which, until recently, has been subject to little change since it was first invented in the early part of the 20th century. This is a very mature chemical technology, but legislation changes in recent years has impacted the industry significantly.

Chlorinated hydrocarbons have historically been the solvents of choice for vapour degreasing – compatible with most materials, stable in use, producing a non-flammable saturated vapour heavier than air at a temperature greater than ambient.  Traditional solvents such as trichloroethylene exhibited all these characteristics but concerns about its carcinogenic properties and the danger to operators by exposure, led to a continuing search for a safer alternative.  1,1,1 trichloroethane based formulations became popular in the last century as a safer replacement. Although safer for users, it proved to be depleting the Ozone Layer and was subsequently banned. N-Propyl bromide (nPB) based formulations became popular in the last part of the century as a safer replacement, but this was later put in Annex 14 of REACH by the EU and can no longer be used as a vapour degreasing solvent in Europe.  Countries around the world are now setting increasingly stringent environmental legislation to control emissions of Ozone Depleting and Global Warming industrial cleaning solvents. This has led to new chemical formulations being developed for industry.

Over 20 years of innovation for industry
EnviroTech Europe Ltd have been supplying vapour degreasing solvent formulations for over 20 years, constantly responding to regulatory requirements for environmental and safety laws and the need for improved standards.  Staff and distributors are highly trained to work with customers to advise on the use of industrial cleaning solvents, helping them to navigate through legislative changes and ensure their vapour degreasing and cleaning solutions remain within regulatory boundaries.

Customers may have recently read in the industry press about another major industrial supplier ceasing production of their range of fluorocarbon containing metal degreasing and vapour degreasing solvents. They may be concerned that other major suppliers will follow suit.

Envirotech Europe would like to assure the industry of its intention to continue the manufacture of its ProSolv®  range of metal cleaning and vapour degreasing solvents for the foreseeable future.

Vapour Degreasing Solvents

Zero Ozone Depletion Potential (ODP) and very low Global Warming Potential (GWP) solvent blend for high performance vapour degreasing

ProSolv® 5408e ticks all the boxes with the perfect profile for a vapour degreasing solvent, developed by EnviroTech Europe Ltd for precision parts cleaning or cleaning automated machinery at strip down.

Vapour degreasing – A guide for production engineers

Vapour degreasing - guide for production engineers

Vapour degreasing – A guide for production engineers

This guide for production engineers explains why vapour degreasing is the most effective and economical process for cleaning of manufactured components.  The start of a new year is always a good time to review your existing cleaning process and ask yourself  ‘am I using a safe modern solvent for vapour degreasing?’.

Vapour degreasingVapour degreasing is the simplest but most effective degreasing and cleaning process which, until recently, has been subject to little change since it was first invented in the early part of the last century. This is a very mature chemical technology which legislation is now effecting changes so fundamental that the more accurate name for the process “Condensation Cleaning” should be used to reflect the improvements in equipment design, chemistry, reduced emissions, economies in usage of solvents and the subsequent environmental acceptability compared to the open topped tanks so ubiquitous in factories and workshops worldwide. The alternatives in equipment design offer differences in technology, which guarantee the continuing use of this process in the future, need to be considered and understood.

The cleaning tank in the corner of most engineering shops hides a very well researched process using sophisticated chemistry. Its popularity is in its simplicity. The tank sump is heated, fitted with cold coils around the internal surfaces at the top to retain the vapour.  Fill to a few centimetres with a non-flammable solvent able to dissolve contaminants, boil to form a vapour 3 to 4 times heavier than air to fill the tank. Hot solvent vapour condenses on the cooler target parts at workplace temperature. The hot liquid solvent dissolves oil and grease and other contaminants. Used solvent returned to the sump revaporises continuing the cycle until parts have achieved the same temperature as the vapour when, with no further condensation, the process is complete. Simple but perfect. Highly productive and economical, parts removed from the cleaning process are clean, warm, and dry in 5 to 10 minutes.

cleaning tank Historically chlorinated hydrocarbons have been the solvents of choice for the “Condensation Cleaning” process. Compatible with most materials of manufacture, stable in constant use, producing a non-flammable saturated vapour heavier than air at a temperature greater than ambient.  In Europe, the United States and in other advanced industrialised economies increasingly stringent legislation to control emissions of VOCs, especially solvents, has led to new formulations for paints and other coatings where water replaces most of the solvent. In the early days the quality of water-based paints was not as good as traditional solvent-based coatings, but innovation has driven the development of new polymers with results as good as, if not better than, the solvent-based originals.

As with coatings, cleaning systems have had to change. With increasingly demanding standards of cleaning required for precision engineering, electronics, optics etc solvents are often first choice, for reasons outlined above, but these have been targeted by regulators and alternatives are encouraged by the relevant authorities and law makers often without serious consideration of unintended consequences. For example, water-based cleaning is encouraged as the obvious alternative, but this has many disadvantages compared to condensation cleaning as although the machines are simple and relatively cheap the processes require multiple heated tanks for immersion or spray processing or long programmed cycles in batch machines for cleaning, rinsing, and drying. Water based processes are slow, energy intensive and occupy more floor space than solvent-based condensation cleaning equivalents where only one tank with a small footprint is needed, delivering shorter process times and, most importantly for the environment, using minimal energy.

The ideal cleaning process would be “Condensation Cleaning” using water but due to the physical characteristics of the water vapour/steam and the inability to carry onto the surface of the targeted parts surfactants to remove the oil, grease and soils and the difficulty and expense of rinsing and especially drying this can only ever be a dream.

Historically chlorinated hydrocarbons have been the solvents of choice for the “Condensation Cleaning” process. Compatible with most materials of manufacture, stable in constant use, producing a non-flammable saturated vapour three to four heavier than air at a temperature greater than ambient.  The traditional solvents such as trichloroethylene exhibits all these characteristics however concerns about its carcinogenic properties and the danger to operators by exposure, led to a continuing search for a safer alternative. 1,1,1 trichloroethane based solvent formulations became popular in the mid part of the last century as a safer replacement. An excellent solvent, safer for users, it proved to be depleting the protective ozone layer around the Earth and was subsequently banned. With the development of the REACH legislation in Europe, trichloroethylene was again allowed with restrictions and stringent controls for use in authorised machines which control emissions to very low figures close to zero.

Soft on the environment and safer for users with high performance, improved cleaning, and lower costs. Lower boiling point, economical with energy with low solvent losses, faster production, reduced costs, easy handling. Exceptionally low surface tension to penetrate micron sized holes and close contact surfaces. Sustainable and secure for future use as your ‘forever solvent’.

ProSolv Benefits

Sealed Tanks
As with all legislation for chemical use regulation and restrictions drive development of associated processes and equipment. Sealed tanks are now standard with many different designs available. The most common are discussed below.

The single tank hermetically sealed machines favoured by some manufacturers uses a process tank to contain the solvent and a separate storage tank/vapour generator. Baskets loaded with parts to be cleaned are introduced from the top or through access points on the side of the tank. Lids or doors hermetically seal the tank. Solvent is pumped into the process tank where agitation, ultrasonics or pumped liquid is circulated through the parts. Used Solvent is removed to the vapour generator, condensing coils controlling the vapour are linked to coils located in the vapour zone which, when the cycle is complete, collapse the vapour.  The process tank is emptied. Controlled air introduced to process tank is then recycled through carbon absorption units to remove traces of solvent until the concentration is within regulatory standards when the lid is released for the basket of parts, clean and dry, to be removed and replaced with a further basket. Variations of process within the hermetically sealed tank are possible using sprays of cold or hot condensed solvent, immersion with or without ultrasonics and revolving baskets to cover most of the problems experienced when processing machined and fabricated parts. Continuous external distillation of the contents of the vapour generator is also an option depending on contamination.

The alternative technology is much simpler and uses well tried techniques not requiring the long recovery times of the hermetically vacuum sealed processes. The multilevel system uses a standard vapour degreasing tank design with a sealed loading section above the process tank. Components to be cleaned loaded in work baskets or jigs are fed to the load section by hand or conveyor, an internal platform raises and lowers the baskets in controlled cycles.

Loading complete – the load enclosure is sealed to completely isolate the process. Then seal on the process tank is opened and the basket automatically lowered into the cleaning section which can be simple condensation cleaning or immersion cleaning with or without ultrasonics or power sprays. Revolving baskets can also be added to improve cleaning in blind or through holes or oil ways in castings and fabrications.

On completion the basket rises to the area where the condensation coils are located, and parts allowed to drain and dry, basket raises into the load section when the process tank is sealed. A fan circulates air within the load area which can be recycled through carbon absorption systems if no external exhaust is preferred.

As baskets entering the loading space contain parts drained and dried only very small amounts of solvent are carried in the exhausted air which is monitored to ensure compliance with appropriate legislation. When this is complete the seal opens fully for removal of cleaned components. The loading section can be fitted with top or side seals allowing baskets to flow through on conveyor systems or be removed by hand or hoist. No solvent enters the work area. Both processes will produce parts cleaned to the highest standards but the choice of which offers the best solution needs a little more consideration.

The hermetically sealed vacuum process is complicated with the need to move liquids in the machine. It is relatively slow as the carbon adsorption process has to remove high levels of solvent from the recirculated airstream from the process tank. This is inefficient as adsorption rates for carbon fall rapidly with increasing saturation.  Final levels of solvent in the tank when the lid or loading door opens will be dragged into the workshop and the area where the operator is working. Long process cycles reduce throughput.

The simpler multilevel systems where movement of liquids is not required are more efficient and offer much faster process times.  Cost of manufacture is also reduced as no liquid movement or vacuum is involved. The extracted loading section ensures no leakage of solvent into the work area giving complete safety for operators and factory staff. Envirotech Europe also offers workplace air monitoring to ensure VOC’s from the solvent are within exposure limits and your machine is operating to specification.

Condensation cleaningConclusions
Both designs of process machines discussed above fully comply with the emission regulations of the EU and U.S authorities. Which to choose will depend on many factors which should be discussed with equipment and solvent suppliers who have the experience to advise on which offers the best process for the application. Equipment and solvent must work together, so it is advisable to ensure that the suppliers co-operate to offer a package with high levels of responsible care and product stewardship to ensure the best and safest installation. EnviroTech personnel and distributors are trained to work with equipment suppliers to advise on the use of ProSolv® 5408e vapour degreasing solvent for the most satisfactory outcome.

The “Condensation cleaning” process still gives the highest levels of economical cleaning with minimum energy usage, low footprint on the factory floor, safety for the operator, and high production rates with low solvent usage and environmental impact. With the new generation of sealed cleaning machines its future as the process of choice is assured.

Video: ProSolv 5408e – Vapour degreasing cycle using hermetically sealed equipment

Vapour degreasing cycle using hermetically sealed equipment.

ProSolv 5408e is a high- performance solvent cleaner used for sustainable and future proof vapour degreasing.  Soft on the environment and safe for users, it offers improved cleaning at lower costs. Low boiling point, economical with energy with low solvent losses, faster production.

Innovation driven by legislation
Vapour degreasing, with or with-out ultrasonics, is the oldest, simplest and most effective solvent degreasing and metal cleaning process used today. It has, until recently, been subject to little change since it was first invented in the early part of the last century. In the UK, Europe, United States and other advanced industrialized economies increasingly stringent legislation to control emissions of VOCs, Solvents with a high Global Warming Potential (GWP), or a high Ozone Depletion Potential (ODP), and those compounds associated with human health concerns has led to Envirotech Europe manufacturing new formulations for precision cleaning solvents with low or near zero potential.​

Halogenated hydrocarbons are the solvents of choice for vapour degreasing and cleaning. The process is essentially simple. A tank with a sump to contain the solvent, heaters at the base and condensation coils around the top section to control the height of the vapour is all that is needed. When heated in the sump halogenated solvents produce, in most cases, a saturated vapour between 3 and 4 times heavier than air at a temperature greater than the ambient temperature of the parts to be cleaned. This allows the solvent vapour to condense on the surface of the parts. The condensate dissolves the contaminants such as oil, greases, flux, and soils returning the used solvent into the sump of the machine for recycling into vapour which continuously condenses onto the parts until they have achieved vapour temperature when, with no further condensation, the process is complete. Parts removed from the cleaning machines are very clean, warm and dry.

The most common halogenated solvents, in use for commercial purposes, are non-flammable so present no risk in this process. Perchloroethylene, used mainly for dry cleaning, methylene chloride previously used widely in paint strippers, 1,1,1- trichloroethane and trichloroethylene used for vapour degreasing were the original materials used based on chlorine chemistry. However continuing concern about the environmental impact and danger to operators by exposure to chlorine-based solvents, especially trichloroethylene, has led to a continuing search for safer alternatives, such as ProSolv 5408e , a trans-1,2-Dichloroethylene based solvent mixture that is non-flammable.

The ProSolv 5408e vapour degreasing process gives the highest levels of economical cleaning with minimum energy usage, low footprint on the factory floor, safety for the operator, and high production rates with low solvent usage or environmental impact. With the new generation of sealed cleaning machines its future as the process of choice is assured.

Industrial solvent cleaners

Clarea® general purpose industrial solvent cleaners are safe for users and the environment

industrial solvent cleaners

Clarea® non-chlorinated industrial solvent cleaners are compatible with all metals, composites and most plastics used to remove dirt, oil, grease, or other contaminants from surfaces without causing harm or leaving residue. They are used as immersion cleaners for component cleaning in manufacturing and engineering industries and as wipe cleaners for large surface areas prior to painting or powder coating. The environmental concerns and health hazards of the chlorinated solvents used as industrial degreasing agents has led to the formulation of this EnviroTech range of safer cleaning solvents.

What to consider when choosing suitable solvent cleaning products?

Solvents used for cleaning must be highly refined and leave no residues on drying. They need to be highly effective removing oils and soils without causing damage or corrosion of the parts or components being processed and leave minimal residues.

Cleaning specifications vary widely from very demanding automotive and aerospace applications to less demanding applications where critical cleaning is not needed such as pre-used parts or assemblies from the transportation, aerospace, or manufacturing equipment sectors. Heavily contaminated when removed from service these must be free of oils, soils, grease and dirt before disassembly prior to refurbishing and rebuilding. Much of this work will be manual and the considerations for the safety of operators, hand wiping or brush cleaning is paramount.

Clarea® products are aliphatic hydrocarbon based low odour degreasing solvents with specified flash points. They will remove oils, greases, hydraulic fluids cutting fluids and a wide variety of hydrocarbon based protective coatings. Clarea® solvents can be safely used with all metals and composites and most plastic and paint finishes.

Clarea® HC40 is low odour degreasing fast drying solvent with a flash point of 40°C. It is suitable for ultrasonic and dip systems and can be used with brush or in hand-wipe processes.
