Publication number: 20030158282Abstract: The invention relates to powder coating material curable with high-energy radiation, comprising an unsaturated polyester resin (A) and a polymeric crosslinker (B) containing, based on the polymer main chain, terminal and/or pendant propenyl, butenyl and/or isoprenyl groups. The unsaturated polyester resin (A) and/or the polymeric crosslinker (B) comprise structural units of the general formula I and/or II. These novel powder coating materials are curable with high-energy radiation, preferably UV light, and are notable in particular for a very good viscosity stability during the preparation, in the melt, of the resins and the compounding of the coating materials, for outstanding coating properties, and for a low oxygen sensitivity on curing. The films resulting after the cure, moreover, exhibit outstanding elasticity.Type: ApplicationFiled: October 22, 2002Publication date: August 21, 2003Inventors: Rainer Blum, Horst Hintze-Bruening, Uwe Meisenburg

Patent number: 6572932Abstract: The invention comprises a composition and method for controlling the gloss of surface covering products through curing of the composition to create a wearlayer surface, and preferably on a floor covering product. The surface covering product preferably is prepared by application of an aromatic polyester acrylate composition including a flatting agent and/or hard particles, and at least one free-radical generating compound to a substrate, and then the coating is partially cured by exposure to low peak irradiance UV light in either ambient or inert air, followed by fully curing the coating with high peak irradiance UV light in preferably an inert atmosphere to form a low gloss abrasion resistant wearlayer surface. Alternatively, a high gloss wearlayer surface is obtained by solely exposing the preferred composition to high peak irradiance UV light in ambient atmosphere. Furthermore, a differential gloss flooring product is obtained by using the present inventive method described herein.Type: GrantFiled: January 31, 2002Date of Patent: June 3, 2003Assignee: AWI Licensing CompanyInventors: Gary A.
