The present invention includes matte textured powder monocoat coating compositions that can be used to coat substrates, such as automobile bodies, and methods of coating such substrates. A powder coating composition may comprise an acrylic resin, a UV light stabilizer, a matting agent, and a texturing additive, wherein the cured powder coating composition transmits less than about 0.1% of UV light at 290 nm and less than about 0.5% of UV light at 400 nm.

Matte textured powder monocoat coating compositions

The powder coating composition of the present invention includes a low-temperature mixture of a powder (A) and a powder (B), in which at least the powder (A) includes an unsaturated polyester resin and a free radical initiator for initiating polymerization of unsaturated polyester resins in the powder coating composition and the powder (B) includes a polymerization promoter and methods for making the composition. The powder (B) may further include an unsaturated polyester. The powders (A) and (B) are physically mixed at temperatures below which the polymerization promoter would cause the free radical initiator to initiate polymerization of the powder coating composition. Subsequently, the physically mixed powder coating composition is applied to a substrate and cured, during which the polymerization promoter causes the free radical initiator to initiate the curing reaction.

Powder coating composition comprising unsaturated polyesters and uses thereof

A thermosetting powder paint coating containing a polymeric binder comprising a polyester graft acrylic copolymer and a low molecular weight crystalline polyester. The coatings can be pigmented or non-pigmented. The polyester-graft-acrylic copolymer can be self-crosslinking by the inclusion of beta-hydroxy ester groups or crosslinked by an external crosslinker.

Polyester-arcylic graft polymers for use in powder coatings

Polyester-acrylic graft polymers for use in powder coatings

A thermosetting paint coating composition is based on a thermosetting polymeric binder comprising a hydroxyl functional polyester polymer and a beta-hydroxy ester acrylic copolymer, where the polymer and copolymer are adapted to crosslink by transesterification in the presence of certain transesterification catalysts.
