More Information
Summary:An epoxy resin composition comprises an isocyanate modified epoxy resin, which is a reaction product of (a) a multi-functional epoxy resin having an epoxy functionality of greater than about 2.2 and (b) a diisocyanate compound. An epoxy powder coating composition comprises the epoxy resin composition. The isocyanate modified epoxy resin has a high resin softening point and a high cross-linked glass transition temperature Tg for powder coating applications.
