The composition is useful as a radiation curable coating, as an adhesive, a photodefinable coating, or as a thermal cure coating. The cycloaliphatic epoxide resin adds toughness and adhesion to the composition, whereas either of the carbinol functional silicone resin or the anhydride functional silicone resin provides the composition with water resistance, weatherability, thermal stability, and flexibility.Type: ApplicationFiled: October 20, 2005Publication date: February 19, 2009Inventors: Glenn Viaplana Gordon, John Bernard Horstman, Randall Gene Schmidt, Gary Michael Wieber, Arthur James Tselepis

Patent number: 7456231Abstract: An article suitable for use as an insulating or coating material comprises a radiation-crosslinked composition comprising a polyethylene, a polypropylene and optionally an ethylene-propylene elastomer. The polyethylene component is selected from high density polyethylene (HDPE), medium density polyethylene (MDPE) and linear medium density polyethylene (LMDPE) and the polypropylene component is either a homopolymer or copolymer. The composition is predominantly based on the polyethylene component and contains the polyethylene component in an amount of at least 50 percent by weight. The article is radiation-crosslinked to a sufficient degree that it possesses thermoset properties, such that when the article is heated to a temperature above the crystalline melting point of the polypropylene homopolymer or copolymer, it is softened but does not become liquid.Type: GrantFiled: February 2, 2005Date of Patent: November 25, 2008Assignee: ShawCor Ltd.Inventors: Peter Jackson, Marcus P. Heydrich, Karen Schnuelle

Patent number: 7446133Abstract: Anti-glare film including anti-glare layer. The anti-glare film is obtained by coating or casting a liquid composition containing a polymer, a curable resin precursor, and a solvent on a transparent plastic film, evaporating the solvent, forming a phase separation structure by spinodal decomposition, and curing the curable resin precursor by irradiation with light. The disclosed anti-glare film prevents reflection of surrounding scenery and dazzle in a display surface.Type: GrantFiled: July 2, 2007Date of Patent: November 4, 2008Assignee: Daicel Chemical Industries, Ltd.Inventors: Hiroshi Takahashi, Hiroaki Ushida
