Advantages︰ GPM-830 CB is a mercaptan-based epoxy
hardener which provides gel time of approximately
30 minutes with a standard bis-phenol A epoxy
resin mixed at a 1:1 ratio under ambient
conditions.
Additional Data:
GPM-830 CB is a mercaptan curing agent that
improves bonds between glass and metal,
especially brass and bronze.
This material is ideal for two-component mixing
equipment in assembly line use when mixed at a
1:1 epoxy/hardener ratio.
GPM-830 CB can be used as a catalyst or cocuring
material where it will impart properties
typical of mercaptans and provide improved
adhesion.
