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.
