Abstract
Novel organofunctional (ketoximino) silanes, such as acetoxyethyl tris(methylethylketoximine)silane, are provided which are useful as crosslinking agents chain-extending agents and chain-terminating agents in room temperature vulcanizable silicone elastomers. The room temperature vulcanizable compositions containing these novel organofunctional tris(ketoximino) silanes, which are stable free flowing fluids in the absence of moisture but cure to the rubbery, solid elastic state upon exposure to moisture, the method of making the same and the cured products thereof are also provided. The present room temperature vulcanizable compositions are particularly well suited for applications in conjunction with concrete (cement) substrates.
