20080286481 | Thermosetting powder compositions for coatings - The present invention relates to an isophthalic acid rich carboxyl functionalized polyester, containing linear chain aliphatic (poly)ether diols, and to thermosetting powder compositions comprising a mixture of the polyester with a beta-hydroxylkylamide group containing cross-linking agent. The invention also relates to the use of said compositions for the preparation of powdered paints and varnishes for the making of coatings and to coating obtained therewith. | 11-20-2008 |
20100310801 | POWDER COMPOSITION - There is described a powder coating composition suitable for food contact use comprising a mix of: (A) a first polyester that is amorphous and COOH functional being obtained from IPA and/or TPA and no more than 10 mole % neopentyl glycol (NPG); (B) a second optional COOH functional polyester obtained from analiphatic diacid and analiphatic diol, and (C) a curing agent that comprises functional groups reactable with the COOH of the polyester(s). The powders are suitable for coating the interior of metal cans especially those holding alcoholic beverages. | 12-09-2010 |
20110166286 | POLYMER COMPOSITIONS - There is described a powder composition curable by radiation and thermally, comprising a mixture of (a) from about 1% to about 15%, by weight of the mixture, of a polyester of T | 07-07-2011 |
20120107629 | LOW TEMPERATURE CURE POWDER COATING COMPOSITIONS - 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, fibre 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. | 05-03-2012 |
20120220676 | POLYESTERS FOR COATINGS - The present invention relates to polyesters that can be prepared from renewable resources and/or recycled materials, to their use and their production process. In particular there are provided hydroxyl-functional or carboxyl-functional polyesters comprising moieties of (e) terephthalic acid and/or isophthalic acid, (f) ethylene glycol, (g) a dianhydrohexitol, and of (h) one or more linear chain dicarboxylic acids; wherein the polyester has a number average molecular weight, as measured by gel permeation chromatography, of from 400 to 15000 daltons, more preferably from 550 to 15000 daltons. Polyesters of the invention can basically be prepared from recycled polyethylene terephthalate and from renewable polyacids and/or polyols. The present invention further provides a process to produce such polyesters via glycolysis of a polyethylene terepthalate and/or a polyethylene isophthalate with a dianhydrohexitol. | 08-30-2012 |
