Abstract: Provided is a method for providing a substrate with an ablative coating using a one-part room temperature curable and sprayable ablative silicone composition. The one-part room temperature curable and sprayable ablative silicone composition is generally thixotropic and cures in depth within 24 hours to provide an ablative or thermal protective layer on an article. The one-part room temperature curable and sprayable ablative silicone composition is substantially free from diluents or solvents. An article having such a coating and the use of the one-part room temperature curable and sprayable ablative silicone composition in the preparation of such an article are also provided.

Abstract: This disclosure relates to continuous methods of making foamed silicone elastomers. This disclosure also relates to compositions used for forming foamed silicone elastomers. The compositions comprise: (i) an organopolysiloxane having at least two silicon-bonded unsaturated groups per molecule; (ii) an organohydrogensiloxane having at least two silicon-bonded hydrogen atoms per molecule; (iii) a hydrosilylation catalyst; and (iv) a physical blowing agent. Foamed silicone elastomers can be prepared from such compositions, using, for example, the methods disclosed herein.
