  • Publication number: 20100233474
    Abstract: A laser-weldable flame-retardant resin composition (for a member located in a transmitting side) comprises (A) a polyester-series resin and (B) at least one phosphinic acid compound selected from the group consisting of a salt of a phosphinic acid, a salt of a diphosphinic acid, and a polymer thereof (preferably, a metal salt). The resin composition may have a laser light transmittance of not less than 15% for a molded product comprising the resin composition and having a thickness of 2 mm. The resin composition may further contain a fluorine-containing resin, a nitrogen-containing flame retardant (e.g., a salt of a triazine compound with cyanuric acid and/or isocyanuric acid), and/or a filler (e.g., a glass fiber), and others. Such a resin composition realizes both of laser-weldability (laser transmissivity) and flame retardancy at high levels.

  • Publication number: 20100227143
    Abstract: A thermoplastic copolyester composition that is able to maintain its color and mechanical strength after exposure to full weathering is provided. More specifically, a stabilizing system is employed in the composition that contains a mixture of one or more light stabilizers (e.g., hindered amines, UV absorbers, etc.), antioxidants (e.g., sterically hindered phenols, organophosphorous compounds, etc.), and secondary amines. By selectively controlling the type and concentration of the stabilizers, the present inventor has discovered that a composition may be formed that is generally resistant to color change and crazing (i.e., micro-crack formation) upon weathering. In addition to a stabilizing system, a processing stabilizer is also employed in the copolyester resin that includes a metal salt of a fatty acid having a chain length of greater than 22 carbon atoms.

  • Patent number: 7772304
    Abstract: A curable coating composition includes a plasticizing component. The plasticizing component includes an isocyanurate core and at least one low surface tension group pending from the isocyanurate core. The low surface tension group may be a) a fatty chain includes at least 6 carbon atoms, b) a silicon-containing group having at least 1 silicon atom, c) a fluorocarbon, and combinations thereof. The low surface tension group may have cross-linkable functional groups pending therefrom. In addition to the plasticizing component, the curable coating composition further includes a resin component and a crosslinking agent that is reactive with the resin component. The curable coating composition including the plasticizing component is capable of forming a cured film that has resistance to both cracking and etching that, to date, has not been achieved with known plasticizing components.
