  • Patent number: 5371139
    Abstract: The present invention relates to a silicone rubber microsuspension which has an excellent high-concentration storage stability, and to a method for the preparation of a silicone rubber microsuspension. The silicone rubber microsuspension comprises a microparticulate silicone rubber having an average particle diameter not exceeding 10 micrometers, a nonionic surfactant whose HLB value is less than 10, a nonionic surfactant whose HLB value is at least 10, and water, with the proviso that the content of the microparticulate silicone rubber in the silicone rubber microsuspension is at least 50 weight percent. The method for the preparation of said silicone rubber microsuspension comprises mixing a liquid silicone rubber composition, a nonionic surfactant having an HLB value of less than 10, a nonionic surfactant having an HLB value of at least 10, and water.

  • Patent number: 5082891
    Abstract: The curable resin composition of the present invention consists of a curable resin having uniformly dispersed therein particles of a cured silicone rubber obtained from an organosiloxane composition curable by a platinum-catalyzed hydrosilation reaction, wherein said organosiloxane composition contains reaction products of an ethylenically unsaturated epoxy compound and an ethylenically unsaturated aromatic compound with the organohydrogenpolysiloxane present in said organosiloxane composition. Either or both of the epoxy compound and the aromatic compound can be prereacted with a portion of the silicon-bonded hydrogen atoms of the organohydrogenpolysiloxane.

  • Patent number: 4880882
    Abstract: The curable resin composition of the present invention consists of a curable resin and the spherical microparticles of cured silicone rubber obtained by the curing of an addition reacting silicone rubber composition, wherein the silicone rubber composition also contains an epoxy compound having an aliphatically unsaturated group. Furthermore, because the microparticles are prepared from an aqueous emulsion or aqueous dispersion of the silicone rubber composition, it has an extremely small particle size.
