Abstract: A method for adhering a second silicone resin hard coating composition to the surface of a scratched or marred first silicone resin hard coating composition comprising etching the surface of the first hard coating composition with a caustic solution, rinsing and drying said first hard coating composition, applying a curable second silicone resin hard coating composition to said first silicone resin hard coating composition, and curing said second silicone resin hard coating composition. A tint can be applied to a theretofore clear substrate by including a tint or dye in the second silicone resin hard coating composition.

Abstract: There is provided flame retardant thermoplastic compositions and masterbatch formulations effective for rendering thermoplastics flame retardant. A typical flame retardant composition could be comprised of 50 to 97 percent by weight of thermoplastic, 1 to 40 percent of a silicone base such as a linear silicone fluid or gum, 1 to 20 percent of a metal organic compound such as magnesium stearate, and 1 to 20 percent of a silicone resin such as MQ resin which is soluble in the silicone base.

Abstract: A SiH-olefin platinum catalyzed composition having a Durometer Hardness of at least 60 where the novel ingredients are a combination of 10 to 50 parts by weight of fumed silica and 5 to 50 parts by weight of calcined diatomaceous earth per 100 parts of the base vinyl-containing compound. Such a composition is useful for forming molded parts in liquid injection molding machines, both of the plunger type and of the reciprocating screw type.
