Patent number: 8901250Abstract: The present invention relates to a powder coating composition for low temperature cure which comprises a mixture of a carboxylic acid group containing first polyester; at least one of a second polyester having a glass transition temperature ?45° C. and/or a crystalline polycarboxylic acid; a glycidyl group containing acrylic copolymer; a further compound and/or resin having functional groups readable with the carboxylic acid groups; and a thermosetting curing catalyst. These thermosetting powder coatings are designed for coating heat-sensitive substrates such as wood, fiber board and other materials which can not withstand the excessive heat/time conditions necessary to cure traditional coatings. The powder coatings of the invention, when cured at temperatures below 150° C., produce a finish which exhibits a high gloss, smooth surface along with an outstanding hardness and weatherability.Type: GrantFiled: June 28, 2010Date of Patent: December 2, 2014Assignee: Allnex Belgium S.A.Inventor: Luc Moens
