  • Patent number: 11952516
    Abstract: A curable silicone adhesive composition comprising adhesion promoter is shown and described herein. The adhesion promoter is a silicon hydride material containing an aromatic based skeleton with another adhesion promoter to provide a silicone material that is curable at relatively low temperatures and shorter time and provides good adhesion to plastics and metal.
    Type: Grant
    Filed: January 23, 2019
    Date of Patent: April 9, 2024
    Assignee: Momentive Performance Materials Inc.
    Inventors: Subrata Mandal, Manav Gupta, Koki Otashiro
  • Publication number: 20230047848
    Abstract: A curable silicone adhesive composition comprising a combination of adhesion promoters is shown and described herein. The composition includes a first adhesion promoter selected from a silicon hydride adhesion promoter and a second adhesion promoter selected from an acrylate functional adhesion promoter to provide a silicone material that is curable at relatively low temperatures and shorter time and provides good adhesion to plastics and metal.

  • Publication number: 20220056326
    Abstract: An adhesive polyorganosiloxane composition includes, at a specific composition ratio: (A) a linear polyorganosiloxane containing an alkenyl group including a low-viscosity linear polyorganosiloxane containing an alkenyl group; (B) a polyorganosiloxane containing at least three alkenyl groups in the molecule; (C1) a polyorganohydrogensiloxane having 3 or more hydrogen atoms bonded to a silicon atom in the molecule; (C2) a linear polyorganohydrogensiloxane having one hydrogen atom bonded to a silicon atom only at both terminals of the molecular chain, and having no aliphatic unsaturated bonds in the molecule; (D) a filler; (E) a platinum group metal compound; and (F) two or more kinds of specific adhesion imparting agent.

  • Patent number: 9034993
    Abstract: A room temperature-curable polyorganosiloxane composition is a two component-type room temperature-curable polyorganosiloxane composition including (A) a base composition and (B) a cross-linking agent composition. The component (A) contains (a1) polyorganosiloxane having a hydroxyl group or an alkoxy group at a molecular end and (a2) an inorganic filler. The component (B) includes (b1) an organosilicon compound having three or more hydrolyzable groups in one molecule, (b2) polyorganosiloxane having an alkoxy group at a molecular end and represented by the following general formula and, and (b3) a curing catalyst. In the two component-type room temperature-curable polyorganosiloxane composition, it is possible to appropriately adjust a compounding ratio of the base component and the cross-linking component according to the use of an automatic mixer/discharger or the like without deteriorating properties such as deep-part curability, curing uniformity, and storage stability.
