Publication number: 20150099818Abstract: A two part composition comprising a Part A and a Part B, wherein Part A comprises an oligomer having both isocyanate and acrylate moieties, and an organic peroxide capable of generating free radicals upon decomposition; and Part B comprises a polyol, and a catalyst that can decompose the organic peroxide. In one form, the two part composition of a Part A and a Part B are in admixture. By combining Part A and Part B the isocyanate moieties react with the polyol to produce a combination of a urethane acrylate oligomer, organic peroxide and the catalyst. Then in either order, the combination is exposed to sufficient actinic radiation to polymerize at least a portion of the urethane acrylate oligomer; and the catalyst decomposes the organic peroxide thus generating free radicals, which free radicals polymerize at least a portion of the urethane acrylate oligomer.Type: ApplicationFiled: October 8, 2013Publication date: April 9, 2015Applicant: DYMAX CORPORATIONInventors: Marufur Rahim, Maria Fe Aton Audia

Patent number: 7247673Abstract: A coating for weatherstrips, windshield wipers, door seals, trunk seals, sunroof seals, windshield seals and the like. The coating comprises a water-based formula that provides high abrasion resistance and, optimally, also provides excellent weathering resistance. The abrasion resistance property is achieved via a combination of boron nitride and a high molecular weight silicone resin. Flexibility and weathering resistance are achieved via the addition of an acrylic/polyurethane/fluoropolymer resin binder blend and high UV-stabilizers and absorbers. Also provided is a method of manufacturing such coatings that comprises the steps of pre-dispersing the boron nitride in water and then combining the pre-dispersed boron nitride with the silicone resin and other ingredients.Type: GrantFiled: February 20, 2004Date of Patent: July 24, 2007Assignee: National Starch and Chemical Investment Holding CorporationInventors: Michael W.
