Trixene® Blocked Isocyanate Prepolymers differ from standard blocked isocyanate crosslinkers by incorporating a more labile blocking agent. It allows them to cure by a chemical mechanism under ambient conditions, rather than by thermal dissociation at elevated temperatures. Their main application is to improve the flexibility, elongation, and impact resistance of epoxy coatings, without compromising chemical resistance. The blocked prepolymers readily react with standard amine hardeners used in 2-K epoxy resin formulations. As such, they can be used to replace part of the epoxy resin component to achieve this desired increase in performance.
