ABSTRACT:
Liquid, high-functional polymercaptan resins employed typically in sealants and adhesives, show excellent catalytic activity for preparing cured epoxy resin compositions from epoxy/anhydride systems. Blends of the epoxy resin with anhydrides and the high functional polymercaptan resins are adapted for room temperature curing into hard resinous compositions. Such compositions cured at ambient temperature show desirable hardness and achieve other characteristics such as reduced water absorption.
