Abstract: This disclosure relates to a process for the preparation of a one component translucent room temperature vulcanisable (RTV) silicone composition. The RTV composition comprises chain-extended alkoxy end-capped polydiorganosiloxane polymers, and tin-based catalysts. The process generates a one component translucent RTV silicone composition which is stable in storage, in the absence of moisture, and is curable in the presence of atmospheric moisture at ambient temperature. The one component translucent RTV silicone composition resulting from the process was unexpectedly found to have excellent adhesive properties towards polyvinyl chloride (PVC) substrates.

Abstract: A one-part room temperature vulcanisable (RTV) silicone composition containing a catalyst comprising (i) a titanate and/or zirconate and (ii) a metal carboxylate salt which cures to a silicone elastomer which may be used as a clear sealant which avoids discolouration and loss of adhesion upon aging.
