GABEPRO® GPM-890 CB
A mercaptan-based epoxy hardener that provides gel time of approximately 90 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. GPM-890 CB is ideal for two-component mixing equipment in assembly line use when mixed at a 1:1 epoxy/hardener ratio. It can be used as a catalyst or co-curing material, where it will impart properties typical of mercaptans while providing improved adhesion.
