GPM-800
A mercaptan-terminated polymer used as a liquid curing agent with unique rapid-cure characteristics for epoxy resins at ambient temperatures. GPM-800 imparts rapid cure rates on systems at low temperatures and in thin films, and is a low toxicity compound with exceptional color. It can also be used to accelerate other epoxy curing agents, such as amines, polyamides and amidoamines.
