Abstract
The invention relates to a vinyl functionalized urethane resin (VFUR) useful as a curing agent in thermosetting powder coating compositions, a process for making said vinyl functionalized urethane resin, a vinyl functionalized urethane resin composition (VFURC) useful as a curing agent in thermosetting powder coating compositions, a process for making vinyl functionalized urethane resin composition, a thermosetting powder coating composition (TPCC), a process for the preparation thereof, a cured thermosetting powder coating composition, processes for coating an article with said thermosetting powder coating composition and an article coated with said thermosetting powder coating composition as well as uses of the vinyl functionalized urethane resin or of the vinyl functionalized urethane resin composition or of the thermosetting powder coating composition or of the articles having coated and cured thereon said thermosetting powder coating composition. The invention relates also to thermosetting powder coating composition useful for powder-in-mold coating articles such as reinforced polymeric e.g. polyester resin articles and to powder-in-mold coating methods employing the thermoset…
