  • Heat cured silicone rubber compositions containing a potassium aluminosilicate filler which provides resistance to hydrocarbon oils and adjustable shrinkage
    Patent number: 5380770
    Abstract: Heat cured silicone rubber compositions which contain a potassium aluminosilicate filler exhibit improved resistance to hydrocarbon oils. The potassium aluminosilicate filler has an average surface area of between about 5.0 and about 6.50 m.sup.2 /g, an average particle diameter of between about 1.0 and about 20.0 micrometers, and an average particle thickness of between about 0.5 and 1.0 micrometers. The filler improves retention of physical properties and resistance to swelling in hot hydrocarbon oils in a wide variety of siloxane compositions.

  • Method for primerless coating of plastics
    Patent number: 4783347
    Abstract: A method for securing protective silicone resin coatings to plastics without the use of primers is disclosed. Shock curing a silicone resin coating composition on transparent plastic substrates, such as polycarbonate, at a temperature not substantially below 140.degree. C. is found to give a tough, adherent coating without distorting the substrate or diminishing its optical clarity, and without the use of primers. The suitability, after incorporation into the silicon resin coating composition, of certain silylated ultraviolet light screening compounds for shock curing is also disclosed.

  • Thermoformable silicone resin coating composition and dual component coating system for polycarbonate
    Patent number: 4559271
    Abstract: Ultraviolet radiation resistant silicone resin coating compositions are provided having improved thermoformability. Improved thermoformability and shortened required aging are achieved by the addition of a Lewis acid compound to the coating compositions is disclosed. Thermoformability is also improved by using the UV screen containing silicone resin coating composition in conjunction with extensible acrylate primers.
