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. In addition, (one-part thermal cure epoxy compound epoxy resin is able to have various different resins).
and requires thermal curing. Table 1 shows the properties and performances of representative polyamines used as curing agents for epoxy resin. 1-1. Aliphatic amine (Three Bond 2103) Aliphatic amine, which rapidly reacts with epoxy resin, is a representative room-temperature curing agent. However, it generates a large quantity of heat and has a
