A mercaptan-based epoxy hardener that provides gel time of approximately 30 minutes with a standard Bisphenol A epoxy resin mixed at a 1:1 ratio at ambient conditions. This material is ideal for two-component mixing equipment in assembly line use when mixed at a 1:1 epoxy/hardener ratio. GABEPRO GPM-830 CB can be used as a catalyst or co-curing material where it will impart properties typical of mercaptans and provide improved adhesion.
