Patent number: 7220802Abstract: A coating composition is produced by forming an aqueous dispersion of a crosslinking agent and a resin that comprises the reaction product of an alkyd polymer, an optional surfalkyd, diacetone acrylamide, another acrylate monomer and optionally aromatic monomers wherein the reaction product is neutralized with either ammonia or an amine. A coating of the aqueous dispersion on wood exhibits at least some of the following desired properties: rapid dry time, good tannin blocking, good resistance to picking up dirt, good hot box stability and good exterior durability. Additionally, the inventive coatings appear to provide improved crosslinking compared to coatings comprising resins not neutralized with an amine or ammonia and/or not containing a surfalkyd.Type: GrantFiled: March 2, 2006Date of Patent: May 22, 2007Assignee: Cook Composites & Polymers Co.Inventors: Tim Julien, Dennis Ryer, John Willhite

Patent number: 6841255Abstract: The present invention includes a co-polymer film which can be applied over a surface of an article to form a continuous surface that is more biocompatible and has a smoother surface morphology than an untreated article. In general the co-polymer film of the invention can be formed by providing a hydrophobic polymer block, such as polydimethylsiloxane (PDMS) with functional —OH end groups and reacting the —OH ends with a conventional monomer or prepolymer of a film-forming polymer capable of reacting with —OH groups. Such reactions are exemplified, using as reactive PDMS a triblock copolymer of the polylactone-polysiloxane-polylactone (PL-PDMS-PL) type, or silicone polyesters. The —OH groups of the polylactone blocks can react with any of a variety of isocyanates in a suitable solvent to form a polymer having PDMS incorporated with its structure.Type: GrantFiled: September 17, 2002Date of Patent: January 11, 2005Assignee: Gambro ABInventors: Reinhold Deppisch, Ulrich Bauer, Werner Beck, Ruth Dietrich, Hermann Göhl, Katja Krämer
