Fiber Resin EY3804 GRAPHITE COMPOSITE REPAIR COMPOUND
EY3804 A/B is a low viscosity, two-component epoxy system that offers low
temperature cure, high temperature strength, and excellent resistance to hot
water immersion. These properties make EY3804 an excellent choice for field
repair of composite components.
EY3804 may be considered as a permanent repair for service
temperatures to 200F. It is also qualified to Boeing specification BMS 8-301J,

designed as a room temperature curing epoxy to develop 300F strength with short
term aging. Cure can be greatly accelerated with moderate heat, as with heat
lamps or a field repair heat source. A heating time of three hours at 150F in
the bond line will provide a full cure.
