An epoxy based adhesive, using a polyamide activator, in general, may be expected to act as an adhesive, sealing compound, or molding compound for both general purpose and structural applications, such as on fairing surfaces. Cured adhesive can be sanded, filed, or machined with conventional tools. This adhesive will bond to steel, iron, aluminum, glass (not Pyrex), concrete, ceramics, porcelain, tile, marble, wood, and thermosetting plastics such as phenolic, polyester, or epoxy. It will bond with less strength to brass, copper, and lead. It is not recommended for nickel, tin, zinc, or thermoplastics such as polyethylene. Proper surface treatment is necessary for all bonds.
