  • Coating composition
    Patent number: 7045004
    Abstract: The present invention relates to a coating composition containing 0.1 to 50 parts by weight of (A) an organosilicate and/or its condensates per 100 parts by weight of a resin solid content in the coating composition, and 0.1 to 50 parts by weight of (B) an acid surface active agent or a boric acid compound per 100 parts by weight of a solid content of the component (A).
    Type: Grant
    Filed: August 30, 2000
    Date of Patent: May 16, 2006
    Assignee: Kansai Paint Co., Ltd.

  • Ordinary temperature curable coating composition
    Patent number: 6509432
    Abstract: An ordinary temperature curable coating composition comprises an oxidative curable silicon modified vinyl-based resin (A) which is obtained by combining an epoxy group-containing vinyl copolymer (a) with an unsaturated fatty acid-containing fatty acid component (b) and a silicon resin (c). The vinyl copolymer (a) is a copolymer of an epoxy group-containing polymerizable unsaturated first monomer and a polymerizable unsaturated second monomer copolymerizable with the first monomer. The silicon resin (c) contains a silicon atom and a hydroxyl group and/or an alkoxyl group which is bonded to the silicon atom. The coating composition can form a coating film superior in weathering resistance, coating film gloss, and coating operation properties such as storage property, initial drying property and brush stroke during double coatings with a brush.
