Patent number: 6828030Abstract: A (poly)oxyalkylene block silyl ester copolymer comprising silyl ester copolymer block units (A) and block units (B), the block units (a) comprising (a) component units derived from a polymerizable unsaturated carboxylic acid silyl ester, and (b) polymerizable unsaturated monomer units other than the component units (a), the block units (B) derived from particular mercapto compounds, and an antifouling paint comprising the (poly)oxyalkylene block silyl ester copolymer. The copolymer enables the formation of an antifouling coating film which exhibits less cracking tendency, excellent adherence, less peeling tendency and controlled hydrolysis rate resulting in excellent antifouling performance and properties.Type: GrantFiled: October 23, 2001Date of Patent: December 7, 2004Assignee: Chugoku Marine Paints, Ltd.Inventors: Hidetaka Arimura, Satoshi Hiyoshi, Naoya Nakamura, Makoto Tsuboi

Patent number: 6797278Abstract: Broadly defined sol-gel films for the coating of solid substrates, wherein such sol-gel films provide effective and durable antimicrobial properties. The utilization of such films permits relatively low-temperature production of antimicrobial substrates, such as ceramics, metals (e.g., stainless steel, brass, and the like), plastics (e.g., polyimides, polyamides, polyacrylics, and the like), glass (e.g., borosilicates, and the like), as compared with typical glazes for ceramics and the like. The inventive films comprise, as the primary antimicrobial active ingredients, certain metal-containing inorganic or organic antimicrobial compounds, such as, preferably, metal-containing ion-exchange, oxide, glass, sulfadiazine, and/or zeolite compounds (most preferably, including silver therein as the metal component).Type: GrantFiled: December 21, 2001Date of Patent: September 28, 2004Assignee: Milliken & CompanyInventors: Delwin Jackson, Leland G.
