Abstract

The invention relates to a resin for powder coatings for use as a top coat in the automotive industry. The invention also concerns top-coated automotive substrates. The resin is an acrylate polymer with several side chains containing unsaturated groups and the amount of unsaturation in the unsaturated acrylate resin is between 213 and 1400 g per mol unsaturated group. The unsaturated group is a (meth)acrylate ester group, an allyl group, a vinyl group or an anhydride containing unsaturated group. The resin results in powder coatings having properties, which makes them very suitable in the automotive industry, especially for use as clear top coats.

Claims

AMENDED CLAIMS[received by the International Bureau on 8 December 1993 (08.12.93); original claims 1, 8 and 9 amended; original claims 3 and 11 cancelled; remaining claims unchanged; claims renumbered 1-14 (2 pages)]
1. Resin for powder coatings for use as a top coat in the automotive industry, characterised in that the resin is an acrylate polymer having several side chains containing unsaturated groups and the amount of unsaturation in the unsaturated acrylate resin is between 214 and 1400 g per mol unsaturated group and wherein the unsaturated group is a (meth)acrylate ester group, an allyl group, a vinyl group or an anhydride containing unsaturated groups.
2. Resin according to claim 1, characterised in that the amount of unsaturation is between 350 and 1000 g per mol unsaturated group.
3. Resin according to any one of claims 1-2, characterised in that the resin is the product of the reaction between an epoxy-functional acrylate polymer and an acid group.
4. Resin according to claim 3, characterised in that the epoxy-functional acrylate polymer is glycidyl (meth)acrylate polymer and the acid group is (meth)acrylic acid.
5. Use of a resin according to any one of claims 1-4 for the preparation of a powder coating for use as a clear topcoat on exterior parts in the automotive industry.
6. Powder paint comprising a resin according to any one of claims 1-4 and usual additives for use as a top coat in the automotive industry.
7. Method for the preparation of a powder paint, characterised in that the softening of the powder paint based on a resin according to any one claims 1-4 takes place through heat and the curing takes place by UV or EB radiation.
8. A partially or wholly top coated automobile body part wherein said top coat is a powder coating obtained from an acrylate polymer having several side chains containing unsaturated groups and the amount of unsaturation in the unsaturated acrylate resin is between 214 and 1400 g per mol unsaturated group and wherein the unsaturated group is a (meth)acrylate ester group, an allyl group, a vinyl group or an anhydride containing unsaturated group.
9. A top-coated automobile part according to claim 8, characterised in that the amount of unsaturation is between 350 and 1000 g per mol unsaturated group.
10. A top-coated automobile part according to any one of claims 8-9, characterised in that the resin is the product of the reaction between an epoxy-functional acrylate polymer and an acid group.
11. A top coated automobile part according to claim 10, characterised in that the epoxy-functional acrylate polymer is glycidyl (meth)acrylate polymer and the acid group is (meth)acrylic acid.
12. A partially or entirely coated wood, plastic or metal substrate, wherein the coating is obtained from a powder coating which is based on a resin composition according to any one of claims 1-4.
13. A method of coating automobile parts which comprises applying to the substrate a top coat based on a resin according to any one of claims 1-4.
14. Resin, use, method, powder paint and coated substrate as substantially described and/or further explained in the examples.
