This invention relates to thermally conductive one-component room temperature vulcanizable organopolysiloxane compositions containing from 30 to 95 percent by weight of filler based on the weight of the composition, of which at least 10 percent by weight of the filler is silicon nitride particles.

Thermally conductive room temperature vulcanizable compositions

A method for improving the adhesion of an amine-containing organopolysiloxane composition to a substrate which comprises coating the substrate with an amine-containing organopolysiloxane composition and thereafter heating the coated substrate to an elevated temperature prior to or during exposure to moisture and carbon dioxide in excess of that present in the atmosphere.

Method for improving the adhesion of amine-containing organopolysiloxane

Polyurethanes having improved properties are obtained from polyester-polyether co-prepolymers. These co-prepolymers are homogeneous, clear liquids of varying viscosity and can be reacted with curing agents to yield clear homogeneous elastomers of various hardness. Cast elastomers prepared from such co-prepolymers have physical properties at least as good as premium polyester urethanes currently available, and have hydrolytic stability and low temperature properties better than such premium polyester urethanes and comparable to premium polyether urethanes, with the cost being comparable to the lower cost of the conventional polyester systems.
