SYNTHESIS OF RESORCINOL - EPOXY ADHESIVE AND EVALUATION OF ITS MECHANICAL PROPERTIES

摘要

A resorcinol-epoxy resin was synthesized which when used as an adhesive gave shear strengths of approximately 1570 psi at 73°F and 2110 psi at 160°F. An average impact strength of 16.8 ft-lb/ 0.75 sq in. of bonded area was obtained at both 73° and 160°F, and 16.4 ft-lb/0.75 sq in. at -65°F when bonding steel to steel.
