Isophorone Diamine—A Curing Agent for Epoxy Resins: Production, Application, Prospects. A Review

This paper describes methods of production and the fields of application of one of the cycloaliphatic amines—isophorone diamine. To develop new adhesive compositions, the effect of the chemical nature of the curing agent (linear and cycloaliphatic amines) on the curing kinetics, as well as the thermomechanical and strength characteristics, of epoxy compositions have been explored. It is found that isophorone diamine-based adhesive compositions have greater viability and improved stress–strain properties than do linear aliphatic amines. It has been shown that various accelerators (derivatives of phenol, imidazole, salts of tertiary amines, etc.) are used to reduce the temperature of postcuring of compositions based on isophorone diamine.
