      Product Details
      • Resists oil, gasoline, and aromatic fuels to protect against exposure to fuel
      • Excellent low-temperature flexibility
      • Meets aerospace industry customer specification requirements
      • Distinct red coloring helps readily identify the coating to maintenance and aviation inspectors
      • Provides good adhesion to synthetic rubber, metal, glass and many plastics

      We developed 3M™ Scotch-Weld™ Fuel Resistant Coating EC-776SR as a general purpose, solvent based adhesive coating that provides good adhesion to synthetic rubber, metal, glass and many plastics. We also added a unique, oil soluble red dye for identification purposes. Our fuel and oil resistant elastomer based coating provides good flexibility across a range of temperatures.

      3M™ Scotch-Weld™ Fuel Resistant Coating EC-776SR is 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 downtimes. 3M Scotch-Weld™ Fuel Resistant Coating EC-776SR can help reduce periodic fuel tank maintenance requirements, costs and downtime.

      We engineered 3M Scotch-Weld™ Fuel Resistant Coating EC-776SR 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.
