SuperCORR A: Electrical Corrosion Prevention for Aerospace, Avionic and Marine Systems
eTravel Wire/10359945

WOKING, U.K. - eTravelWire -- Electrical corrosion costs operators hundreds of billions a year in repaired and replaced electronic and avionic components. EnviroTech Europe supplies SuperCORR A, a specialist barrier film developed for electrical corrosion prevention in aerospace, avionic and marine systems operating in the harshest environments.

Equipment used in adverse conditions is constantly exposed to corrosive gases, salt spray and swings in temperature and humidity, attacking connectors, switches, contactors, bearings and actuators. The risk is acute wherever close-tolerance or dissimilar-metal components meet, as in plated, anodised and galvanised assemblies, where localised galvanic corrosion accelerates failure. Testing shows SuperCORR A significantly reduces "no fault found" incidents, the intermittent failures caused by corrosion at contact points that clear once a component is removed and re-seated.

The proprietary formulation leaves a non-flammable film just 7 microns thick that will not harden, crack or freeze. It displaces fresh and saltwater moisture, forms an airtight seal against sulphur dioxide, nitrogen dioxide, hydrogen sulphide, ammonia and chlorine-based gases, and is inert, neither raising nor lowering contact resistance. Made without sulphates, chlorides, petroleum-based materials or halogens, it meets the EU RoHS directive. Its dual function as corrosion inhibitor and dry lubricant suits close-tolerance assemblies where coating thickness matters.

SuperCORR A was originally developed for the U.S. Air Force and became the industry standard for avionic corrosion prevention among MROs and OEMs. It is approved to MIL-DTL-87177B Type I Grade B, exceeds MIL-C-81309, is listed in the US Tri-Service corrosion manuals and Boeing Part No. 12-371, and has protected the F-16 fighter and the U.S. Navy P-3 Orion. Commercial operators use it on routes involving salt fog exposure and flights over open sea.

For marine corrosion prevention the evidence is equally direct. In a six-month sea spray trial, mild steel panels rusted severely both untreated and when protected with a conventional oil-based corrosion prevention compound, while the section treated with SuperCORR A remained visibly protected, keeping connectors, switches, chains and drive shafts free of corrosion while maintaining lubrication.

Supplied in aerosol cans for application by engineering crews in difficult-to-reach locations, SuperCORR A is manufactured in the United Kingdom and available on short delivery times worldwide.
