  • Patent number: 4555560
    Abstract: A room temperature vulcanizable polyorganosiloxane composition which cures to products, such as silicone rubber, which do not soil easily are made from mixing silanol containing polyorganosiloxane, ketoxime silicon compounds such as organotriketoximosilanes, and organotitanates.
    Type: Grant
    Filed: July 17, 1984
    Date of Patent: November 26, 1985
    Assignee: Toray Silicone Company, Ltd.
    Inventors: Toshio Saruyama, Ryuzo Mikami
  • Patent number: 4552919
    Abstract: A cured product which resists soiling under outdoor exposure obtained from a mixture of a silanol containing polyorganosiloxane having at least one silicon-bonded oxyalkylene radical of the formula --R.sup.1 O(R.sup.2 O).sub.n R.sup.3 and a curing agent.
    Type: Grant
    Filed: June 25, 1984
    Date of Patent: November 12, 1985
    Assignee: Toray Silicone Company, Ltd.
    Inventors: Ryuzo Mikami, Toshio Saruyama
  • Patent number: 4486566
    Abstract: A composition curable at room temperature has resistance to soiling and maintains its adhesion to substrates when cured. The composition is the product obtained by mixing a polyorganosiloxane having at least two silicon-bonded hydroxyl radicals or two silicon-bonded hydrolyzable groups per molecule, a crosslinking organosilicon compound containing at least two silicon-bonded hydrolyzable groups, and an organosulfonate-containing silicon compound.
    Type: Grant
    Filed: March 1, 1983
    Date of Patent: December 4, 1984
    Assignee: Toray Silicone Co., Ltd.
    Inventors: Katsuyoshi Nakasuji, Toshio Saruyama
  • Patent number: 4477606
    Abstract: The water resistance exhibited during the curing of certain moisture curable RTV polyorganosiloxane compositions containing calcium carbonate fillers is significantly increased by treating the calcium carbonate with a hydrophobicizing agent selected from cationic surfactants, nonionic surfactants having HLB values of 10 or less, and organosilanes.
