3M™ Scotch-Weld™ Fuel Resistant Coating EC-776SR is a general-purpose solvent-based adhesive coating that provides adhesion to synthetic rubber, metal, glass and many plastics. We also added a unique, oil-soluble red dye for identification purposes. The 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 premature failure caused by exposure to fuel. The 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 topcoat 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.
