Advanced Corrosion Protection for Avionic, Electrical and Mechanical Systems
Corrosion continues to present a significant challenge for the aerospace industry, affecting aircraft reliability, safety and lifecycle costs. Exposure to moisture, salt-laden air, temperature extremes and airborne contaminants places constant stress on aircraft systems – particularly avionic, electrical and mechanical components where performance margins are critical. Advanced corrosion protection solutions are therefore essential to maintaining airworthiness and operational readiness.
Super CORR A has been developed specifically to address these challenges, providing long-lasting corrosion protection for sensitive aerospace systems operating in harsh environments. Originally formulated to meet demanding military requirements, the product is now widely used across aerospace and defence applications where failure is not an option.
Addressing Corrosion in Aerospace Environments
Aircraft routinely operate in conditions that accelerate corrosion processes, including coastal regions, high-humidity climates and low-altitude missions over seawater. While structural corrosion is a well-recognised concern, corrosion affecting electrical connectors and mechanical flight controls can be equally disruptive.
In avionic and electronic systems, corrosion can increase contact resistance, degrade signal integrity and lead to intermittent faults that are difficult to diagnose. Mechanical components such as flap tracks, screw jacks and control linkages are also vulnerable, particularly where corrosion increases friction or wear, impacting control responsiveness and increasing maintenance requirements.
Dual-Function Protection and Lubrication
Super CORR A offers a combination of corrosion protection and dry lubrication, making it well suited to both electrical and mechanical aerospace applications. When applied, it forms an ultra-thin, hydrophobic protective film – approximately seven microns thick – that actively displaces moisture and inhibits oxidation without interfering with tight tolerances or electrical performance.
The non-hardening film provides sustained protection against atmospheric and salt-induced corrosion while also reducing wear and fretting in moving or vibration-prone components. Unlike traditional waxes or heavy oils, the coating remains stable over time and does not attract contaminants or build up on treated surfaces.
Protection for Avionic and Electrical Systems
Super CORR A is particularly effective in safeguarding aerospace electrical and electronic assemblies, including connectors, switches, wiring harnesses and avionic modules. By preventing corrosion at contact points, the product helps maintain signal integrity and reduces the risk of performance degradation caused by oxidation, electro-migration or fretting corrosion. It has been extensively tested by the US Airforce and proven to significantly reduce instances of “no fault found”.
The formulation is non-flammable, RoHS-compliant and free from sulphates, chlorides and halogens, making it suitable for use on sensitive electronic components and in regulated aerospace environments.
Safeguarding Mechanical Flight Controls
Mechanical flight control systems are exposed to continuous movement and environmental stress, particularly in aircraft operating in maritime or high-humidity conditions. Super CORR A provides a dry lubricating layer that protects these components from corrosion while simultaneously reducing friction and wear.
This dual action supports smoother operation of flight controls and helps extend maintenance intervals, contributing to improved aircraft availability and reduced lifecycle costs.
Supporting Avionic Maintenance and Operations
Supplied in an easy-to-apply aerosol format, Super CORR A is applied efficiently during routine inspections, maintenance and overhaul activities by many military and commercial aviation companies. Its ability to reach confined or hard-to-access areas makes it especially valuable for aerospace maintenance, repair and operations (MRO) teams.
Super CORR A helps aerospace operators reduce unplanned downtime, protect high-value assets and maintain consistent performance in demanding operating environments.
Specialist Barrier Film Corrosion Protection Spray
Super CORR A is a unique and proprietary formulation with long-lasting, anti-corrosion inhibitors.
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. It complies with MIL-DTL-87177B (revised MIL-L-87177A) Type I, Grade B.
Super CORR A forms an airtight seal preventing damage to electronics and other surfaces caused by exposure to acid gases such as Sulfur dioxide (SO2), Nitrogen dioxide (NO2), Hydrogen Sulfide (H2S), Ammonia (NH3), Chlorine based gases (CL12), and the thermal decomposition by product of HFC-227ea used in fire suppression systems, Hydrogen Fluoride (HF).
The use of Super CORR A cannot 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 damaged equipment or a component that failed because of corrosion.
