  • Patent number: 3962160
    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.

  • Patent number: 3941741
    Abstract: Self-bonding, heat-curable silicone rubber composition comprising (a) a diorganopolysiloxane polymer (b) a curing catalyst and (c) a compound of the formula, ##EQU1## where R.sup.6 is selected from alkyl radicals and hydrogen, Z is seleccted from COO, phenylene, CO, CONH and CON-R.sup.2, R.sup.2 is selected from monovalent hydrocarbon radicals and halogenated monovalent hydrocarbon radicals, R.sup.5 is selected from unsaturated monovalent hydrocarbon radicals and unsaturated halogenated monovalent hydrocarbon radicals, G.sup.1 is selected from hydrogen, R.sup.2 radicals and R.sup.5 radicals. There may also be used in the above composition a process aid, a filler, and other ingredients commonly used in heat-curable silicone rubber compositions. In place of the maleate set forth above, and/or in addition to the maleate set forth above, there may be used a silylmaleate.
