摘要:
Embodiments include oxazolidone ring containing adducts obtainable by combining an aliphatic epoxy compound, an aromatic epoxy compound, and a diisocyanate. Embodiments further include a curable powder coating composition including a resin component and a hardener component, where the resin component includes the oxazolidone ring containing adduct.
摘要:
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.

摘要:
A controlled conversion resin having an epoxy functionality of greater than 2 and comprising moieties derived from epoxy resin, dihydric phenol, acid anhydride, or amine. The resin is prepared by reacting an epoxy resin with a dihydric phenol, an acid anhydride, or amine or other branching agent in the presence of a catalyst and terminating the reaction at a point such that the reaction product contains both epoxy and terminal hydroxyl groups.
