3M™ Scotch-Weld™ Fuel Resistant Coating EC-776 is a general purpose, solvent based adhesive coating that provides good adhesion to synthetic rubber, metal, glass and many plastics. Our fuel and oil resistant elastomer based coating provides good flexibility, retaining its flexibility across a range of temperatures.

It’s an ideal solution for protecting many aircraft components that may be damaged or their performance diminished by coming in contact with aviation fuel. Any vulnerable component such as those adjacent to refuel/defuel fittings, fuel dump valves, drain ports, access panels, system plumbing and fuel tank vents will be better protected against pre-mature failure caused by exposure to fuel. Our fuel resistant coating can also be used to coat aluminum or steel fuel tanks using the fill and drain method. Certain additives and other chemicals in aviation fuels can increase the erosion of the fuel tank top coat inside the fuel tank. Inner fuel tank top coatings can peel and generate chips and particles that clog engine fuel filters, increasing maintenance costs and prolonging aircraft down times. 3M™ Scotch-Weld™ Fuel Resistant Coating EC-776 can help reduce periodic fuel tank maintenance requirements, costs and downtime.

EC-776 Fuel Resistant Coating was engineered to meet customer specification requirements for performance and flexibility in the aerospace industry. Under normal atmospheric conditions this coating becomes tack free in about 20 minutes and should thoroughly dry in approximately 24 hours. It may be applied by brush or flow applicator depending on the needs of your process.
