Metal substrate coated with a thermosetting powder coating composition of an acrylic polymer, a hydroxy functional plasticizer and a blocked polyisocyanate cross-linking agent

摘要

A thermosetting polymer powder coating composition comprising finely divided powder particles that have a diameter of about 1-100 microns wherein the powder particles are a blend ofPPA. an acrylic polymer;PPB. a blocked organic polyisocyanate; PPC. a hydroxy functional plasticizer; andP PD. a catalytic amount of an organometallic compound;P PThe thermosetting powder coating composition is particularly useful as an exterior finish for automobile and truck bodies.
