Henkel Corp. (Rocky Hill, Conn.) has introduced Loctite MAX2, a new polyurethane matrix resin designed for use with carbon and glass fiber in the resin transfer molding (RTM) of high-volume automotive parts and structures. Henkel reports that, compared to standard epoxy matrix resins, the new polyurethane formulation cures significantly faster. During injection, it is also said to enable more efficient impregnation without stressing the fibers due to the lower viscosity of the resin. The mechanical properties of Loctite MAX2 were developed to provide flexibility and greater impact resistance than traditional epoxy resins.
