ABSTRACT:
Proposed is a thermosetting powder coating composition comprising a mixture of particles reactive towards one another, optionally in combination with a catalyst, with a portion of the reactive particles comprising a polymer reactive towards oxetane groups while another portion comprises an oxetane groups-containing cross-linking agent having an oxetane functionality of more than 1. The quantity of oxetane oxygen in the cross-linking agent preferably is at least 0.4 wt. %. The reactive polymer preferably is a polymer having groups reactive towards oxetane, such as carboxyl, epoxy, oxetane, anhydride, and hydroxyl, with preference being given to a polyester or a hydroxypolyacrylate.
