SuperCORR A -Advanced corrosion protection for aircraft
Advanced corrosion protection for aircraft – SuperCORR A lubricates and protects mechanical and electrical flight controls in surveillance aircraft.
Super CORR A provides advanced corrosion protection for aircraft – It lubricates and protects mechanical and electrical flight controls and electronic equipment in Lockheed Martin P-3C Orion aircraft flown by air forces around the world for anti-submarine and maritime surveillance, also used in searches for missing ships or aircraft.
The Royal Australian, Korean and Japanese Air Forces were employed in the search for the Malaysia Airlines flight MH370 Boeing 777 passenger jet which disappeared on a scheduled flight in March 2014. The search for debris in a vast area of ocean, bigger than the land area of Europe, southwest of Perth, Australia operated for thousands of hours at low levels but failed to locate any debris and was suspended in 2017.
The maintenance schedules specify Super CORR A to lubricate and protect the flap tracks and screw jacks in the wings of the aircraft which are constantly exposed to extremely corrosive salt laden air as the aircraft in search mode can be flown at very low altitudes of hundreds of feet for long periods.
Super CORR A lubricant and protective coating is widely used by the military, electrical, electronics and aerospace industries for critical applications to give the protection needed in extreme conditions. Super CORR 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 connections for very close spaced connectors, contacts, wiring and moving parts
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, a Type I, Grade B Corrosion Preventative lubricant out-performed 11 other products in comparative testing to identify the best product to protect and lubricate the flap tracks and screw jacks on the aircraft.
The flap tracks, located in the aircraft’s wings, are what the flaps slide on when they move up or down to lower or increase speed. The screw jacks engage and retract the wing flaps. Corrosion on any of the surfaces can lead to snatching or vibration which can affect the pilot’s control
Due to constant operation in salty and corrosive atmospheres which need post-flight rinses and monthly washing down of the aircraft re-lubrication and corrosion treatment for the flap tracks and screw jacks is required each time, with conventional lubricants, to prevent rusting. Super CORR A was evaluated against competitive products under the Federal Test Method Standard #791B, using a five percent Salt Spray Corrosion Test.
Super CORR A far exceeded the performance of the other products evaluated. After over 200 hours of continuous exposure to salt spray corrosion, Super CORR A protection actually increased over time where all the other, similar, products failed early or contributed to an increase in corrosion.
The accelerated salt fog corrosion testing demonstrated that the application of
Super CORR A which complies with MIL-DTL-87177B (revised MIL-L-87177A) also increased electrical operation to 1400 hours versus 100 hours for the control product used at that time. Technical manuals were updated to include the application for electrical and mechanical parts for civilian and military operations.
The most important conclusion from the historical data and prototype testing is the availability of this excellent corrosion preventive compound that has dry film lubricant properties. The application of Super CORR A on aircraft components can reduce maintenance man hours, reduce part replacement costs, increase life of aircraft, safety, and readiness for operations.
Estimates for the maintenance cost for the US Air Force F-16 fleet can reach $500 million per year, the use at all military branches could reach billions of dollars per year. Applications at locations tested by the U.S. Air Force are not normally treated with corrosion prevention and control lubricants (CPC’s). These are the electrical connectors that are susceptible to subtle and not so subtle forms of corrosion that can interfere with the electrical operation of the F-16.
Testing by the U.S. Navy at NADEP Jacksonville incorporates not only electrical connectors, but mechanical and structural components as well. Future uses will also include ground support equipment. The properties of Super CORR A are such that it can be used in a wide variety of applications and on any materials, metal or plastic. Properties of the Super CORR A far exceed the requirements defined by the MIL-L-87177A specification. Many of the beneficial properties of the product are not required in the MIL specification.
EnviroTech Europe is a manufacturer and distributor of anti-corrosion, lubricants and coatings used on wiring, connectors, switches, circuitry, avionics. Read the full report – ‘Use of MIL-L-87177A as a corrosion prevention compound’ in our Library https://www.corrosion-protect.com/resources

Corrosion protection for unpainted metal in highly corrosive environments
Tests demonstrate the amazing properties of SuperCORR 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 part marked #1 was the control and not sprayed with SuperCORR A corrosion protection spray. Half of part marked #2 was sprayed with SuperCORR A and half left uncoated. Component #3 was completely treated with SuperCORR A. 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.
This is especially important in electrical motors and power control systems where these metals are used as conductors or switch contacts on printed circuit tracks and all types of connectors which although sealed in control panels will be exposed whenever the boxes are opened or contactors operated and connectors plugged and unplugged. In most cases it is not possible to paint these conductive surfaces or apply other forms of protection without loss of conductivity leading to arcing or supply failures.
These tests demonstrate the amazing properties of SuperCORR 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.
A trial was set up by the works engineering department at the plant who sprayed a new condenser with an aerosol of SuperCORR A corrosion protection spray. This applies a very thin protective film of a proprietary formulation containing extremely long-lasting anticorrosion inhibitors, which also give superior lubrication coefficients and protect components against moisture. This unique, water displacing lubricant, with synthetic corrosion prevention compounds is tested and proven non-flammable and environmentally friendly without sulphates, chlorides, or other halogens
After a few months the treated condenser showed so little signs of corrosion that further controlled trials were set up to test for long term protection of untreated metal in this extremely corrosive environment experienced in paper and pulp mills, water processing plants and oil drilling rigs.
The improvement is clear and demonstrates the savings in costs of parts and labour for maintenance and replacement untreated metal components exposed to these corrosive conditions.

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

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.
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
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.
