Curing agents for epoxy resins

Abstract

Epoxy resin was discovered in 1938 by Pierre Castan, a chemist in Switzerland. As of 1989, 137,000 tons of epoxy resin had been produced in Japan, and epoxy resin has been used in a wide range of fields, such as paints, electricity, civil engineering, and bonds. This is because epoxy resin has excellent bonding property, and also after curing, it has excellent properties on mechanical strength, chemical resistance, electrical insulation. In addition, epoxy resin is able to have various different properties as it is combined and cured together with various curing agents. This issue describes the types of curing agents for epoxy resin and their characteristics comparing to Three Bond products. The epoxy resin compositions of Three Bond currently on the market are the Three Bond 2000 Series (base agent for epoxy resin), the Three Bond 2100 Series (curing agent for epoxy resin), and the Three Bond 2200 Series (one-part thermal cure epoxy compound resins).
