摘要: This relates to a process for the preparation of a one component translucent room temperature vulcanisable (RTV) silicone composition comprising chain-extended alkoxy end-capped polydiorganosiloxane polymers, and tin-based catalysts. The process generates a one component translucent room temperature vulcanisable (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 room temperature vulcanisable (RTV) silicone composition resulting from this process was unexpectedly found to have excellent adhesive properties towards polyvinyl chloride (PVC) substrates.
