3M™ Scotch-Weld™ Void Filling Compound EC-3524 B/A Off-White, 1 gal kit

3M Scotch-Weld Void Filling and Edge Sealing Compound EC-3524 B/A is a fire retardant, void filling, edge-sealing, potting and complex gap-filling epoxy compound for aerospace weight reduction. It is also effective as an abradable compound in aircraft engines. EC-3524 B/A provides a 90 minute worklife and is fully cured within 48 hours at 75°F (24°C).

EC-3524 B/A is an ideal solution for void filling, edge sealing and as an abradable compound in aircraft engines. 3M formulated the two-part fire retardant epoxy compound with a 90 minute worklife to provide ample time to position parts for fit and keep processes moving forward. It achieves full cure within 48 hours at 75°F (24°C) and is available in blue, off-white or black when mixed. It is a malleable paste with an extended worklife that allows shaping for applications such as a fairing compound for aerodynamic flushness, and can also be used for bonding inserts. As a fire retardant epoxy compound, 3M Scotch-Weld EC-3524 can be used to create an effective seal. Its 100% solids content helps it hold shape as well.
