Hardeners used with epoxy prepolymers

Epoxy resins are the strongest adhesives known. They can adhere to almost any kind of surface and are resistant to solvents and to extremes of temperature. When an epoxy cement is used, a low-molecular-weight prepolymer (the most conunon is a polymer of bisphenol A and epichlorohydrin) is mixed with a hardener—a compound that will react with the prepolymer to form a cross-linked polymer. [Pg.1166]

Epoxy resins represent a class of step-growth polymer familiar to anyone who has used epoxy to glue together a broken object. An epoxy resin consists of two components a fluid prepolymer composed of short polymer chains with reactive epoxides on each end, and a hardener, usually a diamine or triamine that ring opens the epoxides and cross-links the chains together. [Pg.1160]

Epoxy-terminated oxazolidone prepolymers were prepared by using a ratio of NCO epoxide of 1 2. These prepolymers could then be cured with conventional epoxy hardeners or catalysts ... [Pg.1016]
