Air Products offers a complete line of accelerators and catalysts for epoxy formulators. This includes tertiary amines, which cure an epoxy resin by catalytically induced anionic polymerization; imidazoles, which offer a pot life range from a few hours to six months and are excellent accelerators for other curing agents such as dicyandiamide and anhydrides; substituted ureas, which are low-toxicity replacements for Monuron and Diuron as accelerators for dicyandiamides; and amine-blocked acid catalysts, also used primarily as accelerators.
