Developed at our facility in 1966 by Diamond Shamrock, mercaptans are epoxy curing agents with exceptionally rapid cure speed and hardness development properties for DIY consumer, automotive, construction and concrete markets, and various other industrial products. They offer a unique advantage of fast cure for both at ambient and low temperatures, and in thin films. Our wide selection of mercaptans offer cure speeds as fast as 40 seconds to five minutes, and up to 30 minutes. With excellent bond strength to glass, metal, concrete and wood, and fast-set characteristics, our mercaptans are ideal for a number of industrial products and consumer adhesives (such as the “five-minute” consumer adhesives). They can also be used to accelerate other epoxy curing agents, including amines, polyamides and amidoamines.
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.
A low-odor, mercaptan-terminated polymer used as a liquid curing agent with unique rapid-cure characteristics for epoxy resins at ambient temperatures. GPM-800 LO imparts rapid cure rates on systems at low temperatures and in thin films. It 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.
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. 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.
A mercaptan-based epoxy hardener, it is pre-catalyzed and provides fast gel times, including in systems requiring thin films at below freezing temperatures. GPM-845 MT has improved moisture tolerance with a low viscosity that allows it to be used in a variety of applications for curing any epoxy resin.
Amine-catalyzed epoxy curing mercaptan formulated for quick sets at room temperature. GPM-888 can be used as the single curing agent, or as an accelerator for amine or amide chemistries. In addition to low toxicity, GPM-888 has an exceptional low-temperature cure capability and accelerated cure times of three to five minutes.
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.
An easy-to-use epoxy curing agent with reduced odor, GPM-891 provides a non-yellowing casting color. The amine additive in GPM-891 is formaldehyde free and is less sensitive to the addition of a chelator that can be used help reduce skinning problems.
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. GPM-895 FC can be used as a catalyst or co-curing material, where it will impart properties typical of mercaptans while providing improved adhesion.
