  • Publication number: 20120164466
    Abstract: The present invention provides a method for coating a thermoplastic composite comprising the steps of: i) providing a thermoplastic powder coating composition comprising one or more functionalized polyolefins selected from the group consisting of functionalized polyethylenes, functionalized polypropylenes, ethylene acid copolymers, ionomer resins, functionalized ethylene vinyl acetate (EVA) copolymers and functionalized ethylene alkyl(meth)acrylate copolymers, and ii) applying the thermoplastic powder coating composition to the thermoplastic composite to form a powder coating on the thermoplastic composite. The method according to the invention provides a strong adhesion of the thermoplastic powder coating onto the thermoplastic composite, a high scratch and scuff resistance as well as a surface appearance of a high quality finish and outdoor performance.

  • Publication number: 20120029076
    Abstract: The invention provides a micronized polymer powder compos Won for the use in personal care and cosmetics, the micronized polymer powder composition comprising at least one thermoplastic polyester based on at least one diol and at least one dicarboxylic acid selected from the group consisting of cyclic and branched aliphatic dicarboxylic acids having 4-12 carbon atoms and aromatic dicarboxylic acids having 8-12 carbon atoms. The present invention provides also a cosmetic composition comprising the at least one micronized polymer powder composition according to the invention. The composition according to the invention provides a high-performed gentle exfoliation property of skin care and cosmetic compositions without creating micro cuts and irritation of the skin surface while still providing the range of desired care properties.
