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. Pinter, Marufur Rahim

Patent number: 7230064Abstract: A process for the preparation of urethane resins, which comprises the steps of: preparing a product(A) having a hydrolysable group directly bonded to 1–10 silicon atoms and having less than two secondary amino groups in one molecule; preparing a product(B) having a terminal isocyanate group in an amount 4% or less by weight of said product(B); and reacting said product(A) with said product(B) in proportions of at least 0.5 equivalent of the product(A) per free NCO group of said product(B). The process can readily give urethane resins which exhibit excellent storage stability and are enhanced in the degrees of freedom of physical properties of products of curing.Type: GrantFiled: February 28, 2002Date of Patent: June 12, 2007Assignee: Konishi Co., Ltd.Inventors: Shinichi Sato, Akihiro Sato
