CAPCURE® 40 SEC HV

A mercaptan-based epoxy hardener that provides gel times of 40 seconds with a standard Bisphenol A epoxy resin mixed at a 1:1 ratio under ambient conditions. This mercaptan curing agent improves bonds between glass and metal, especially brass and bronze. It is ideal for two-component mixing equipment in assembly line use when mixed at a 1:1 epoxy/hardener ratio. Capcure 40 Sec HV can be used as a catalyst or co-curing material, where it will impart properties typical of mercaptans while providing improved adhesion and applications of mercaptan in glue.
