  • Method of mitigating ice build-up on a substrate
    Patent number: 9090797
    Abstract: The present invention is directed to a method of mitigating ice build-up on a substrate, comprising applying to the substrate curable film-forming compositions comprising isocyanate-functional curing agents, film-forming compositions with functional groups reactive with the isocyanates, acrylic polymers having polysiloxane side chains, and polysiloxanes.
    Type: Grant
    Filed: March 27, 2014
    Date of Patent: July 28, 2015
    Assignee: PPG Industries Ohio, Inc.

  • Method of mitigating ice build-up on a substrate
    Patent number: 8911832
    Abstract: The present invention is directed to a method of mitigating ice build-up on a substrate, comprising applying to the substrate combinations of curable film-forming compositions. The curable film-forming compositions may comprise functional film-forming polymers and curing agents or any of various polysiloxanes and optionally silanes with reactive groups. The film-forming compositions can be applied directly to the surface of the substrate or to a primer coat on the substrate.

  • Method of mitigating ice build-up on a substrate
    Patent number: 8765228
    Abstract: The present invention is directed to a method of mitigating ice build-up on a substrate, such as a wind blade, comprising applying to the substrate curable film-forming compositions comprising isocyanate-functional curing agents, film-forming compositions with functional groups reactive with the isocyanates, and polysiloxanes. The film-forming compositions can be applied directly to the surface of the substrate or onto a primer coat and/or topcoat on the substrate.

  • Method of mitigating ice build-up on a substrate
    Patent number: 8747950
    Abstract: The present invention is directed to a method of mitigating ice build-up on a substrate, comprising applying to the substrate applying to the substrate a curable film-forming composition comprising: (a) a resinous component comprising: (i) a polyepoxide; (ii) a polysiloxane; and (iii) an organooxysilane; (b) a polyamine and/or an aminosilane; (c) at least one additional polysiloxane different from the polysiloxane of (ii) above, and (d) optionally a catalyst. The film-forming compositions can be applied directly to the surface of the substrate or onto a primer coat on the substrate.
