Three Bond Technical News Issued December 20, 1990 32. Curing Agents for Epoxy Resin Introduction _____ . Epoxy resin was discovered in 1938 by with various curing agents. Pierre Castan, a chemist in Switzerland. As of This issue describes the types of curing 1989, 137,000 tons of epoxy resin had been agents for epoxy resin and their characteristics produced in Japan, and epoxy resin has been comparing to Three Bond products. used in a wide range of fields, such as paints, The epoxy resin compositions of Three Bond electricity, civil engineering, and bonds. This is currently on the market are the Three Bond because epoxy resin has excellent bonding 2000 Series (base agent for epoxy resin), the property, and also after curing, it has excellent Three Bond 2100 Series (curing agent for properties on mechanical strength, chemical epoxy resin), and the Three Bond 2200 Series resistance, electrical insulation.
curing agent for epoxy resin, is formed by the condensation reaction between dimer acid and polyamine, and contains reactive primary and secondary amines in its molecules. Polyamide amine reacts with bisphenol-A-type epoxy resin to cure at or below normal temperature with moderate heat generation. It cures so slowly that it has a long pot life.
