Abstract: A polymer composition is disclosed that contains glass fibers and has an excellent balance of properties. The polymer composition displays a comparative tracking index of greater than about 400 volts and a dielectric strength of greater than about 4 kV/mm. In addition, the polymer composition results in excellent surface properties even when molding parts having a long length. The polymer composition can contain at least one stabilizer in combination with a calcium phosphate, such as a calcium hydroxyphosphate. In one aspect, the calcium phosphate is present in the polymer composition in the form of bone char.

Abstract: There is described a primer composition comprising a silicone polyether, a reinforcing filler, one or more polydiorganosiloxane polymer(s) and a carrier and the preparation and use thereof. The primer composition is particularly designed for use with silicone elastomers especially for addition (hydrosilylation) curing silicone elastomers, the preparation thereof, and to a process for improving the adhesion of silicone elastomeric compositions to pre-cured silicone elastomer material substrates. A method for improving the adhesion of silicone elastomer to a pre-cured silicone elastomeric substrate is provided. The method comprises: applying a primer composition to a silicone elastomer substrate; optionally, air-drying (or baking) the primer composition to form a uniform primer film covering the substrate; applying a hydrosilylation curable silicone rubber composition to the substrate covered with the primer to obtain a composite; and curing the composite in order to obtain a silicone elastomer adhesively bonded to a silicone elastomer substrate.
