    摘要: The present invention relates to a shelf stable one component alkoxy-functional RTV composition. In particular, there is utilized a novel end-capping catalyst alone or with a co-catalyst to form a poly-alkoxy terminated diorganopolysiloxane polymer. Such a polymer is formed by reacting a silanol terminal diorganopolysiloxane, either with a polyalkoxy containing silazane cross-linking agent or an integrated cross-linker, scavenger in the presence of the end-capping catalyst.

    摘要: A process of coating a solid substrate with an abrasion resistant silicone hard coating composition which is curable upon exposure to ultraviolet radiation under a non-inert atmosphere, such as air, is provided. The coating composition is comprised of a combination of UV light crosslinkable polyfunctional acrylate monomers, SiO.sub.2 in the form of colloidal silica, and acryloxy functional silanes and a selected blend of ketone-type and hindered amine-type photoinitiators.
