Claims
- 1. A fused powder coating having a wrinkle finish which comprises a thermoset product of the reaction between a hydroxyl-functional resin having a hydroxyl functionality greater than 2, an aminoplast resin as a curing agent, cyclamic acid as the sole catalyst for the reaction as modified by a basic inorganic filler.
- 2. The coating of claim 1 wherein the filler is calcium carbonate.
- 3. The coating of claim 1 wherein the resin is a polyester having a viscosity at 200.degree. C. of from about 17 to about 90 poises.
- 4. The coating of claim 2 wherein the amount of calcium carbonate is from about 15% to about 40% by weight of the combined weight of the hydroxyl-functional resin and calcium carbonate.
- 5. The coating of claim 1 wherein the resin has a functionality of from about 2.2 to about 3.5.
- 6. A powder coating composition comprising a hydroxyl-functional resin having a hydroxyl functionality greater than 2, an aminoplast resin as a curing agent, cyclamic acid as the sole catalyst and a basic inorganic filler, said composition having a hot plate melt flow of from at least about 20 mm up to about 150 mm at 375.degree. F. and a gel time not greater than about 300 seconds at 400.degree. F.
- 7. The coating composition of claim 6 wherein the filler is calcium carbonate.
- 8. The coating composition of claim 6 wherein the resin is a polyester having a viscosity at 200.degree. C. of from about 17 to about 90 poises.
- 9. The coating composition of claim 7 wherein the amount of calcium carbonate is from about 15% to about 40% by weight of the combined weight of the hydroxyl-functional resin and calcium carbonate.
- 10. The coating composition of claim 6 wherein the resin has a functionality of from 2.2 to about 3.5.
