Abstract: The present invention is based on the discovery that a cured organic or organosiloxane gel will enter and flow through a conduit to a dispensing location as a coherent, homogeneous portion of material when (1) one end of the conduit is immersed in the gel (2) a sufficient pressure differential is applied between the surface of the gel and the interior of the conduit to cause the gel to enter and at least partially fill a portion of the conduit, and (3) sufficient pressure is then applied within the conduit to cause the gel to flow in the conduit to at least one dispensing location where the gel is withdrawn from the conduit as an integral, homogeneous stream of material.

Abstract: A method of manufacturing an improved electrical high voltage coated insulator is described. The method involves applying and curing a one-part, room temperature curable silicone composition to the surface of an insulator, the insulator surface having a minimum designated arc resistance. The silicone composition is the product obtained by mixing in the substantial absence of moisture a specified polydimethylsiloxane fluid containing hydroxyl radicals, finely divided aluminum hydroxide filler, a silane of the formula R.sub.b Si(ON.dbd.X).sub.4-b and an optional condensation catalyst. The coating cures on exposure to atmospheric moisture to produce a surface adhered onto the insulator that resists the development of leakage currents and flashover failure upon exposure to electrical stress, moisture, contamination, and other outdoor weathering stresses.

Abstract: A crosslinker-platinum catalyst-inhibitor is prepared by heating in a closed system for 10 to 30 hours at 50.degree. C. to 90.degree. C. a mixture of a siloxane having at least three silicone-bonded hydrogen atoms, an acetylenic alcohol and a platinum catalyst and then removing the unreacted acetylenic alcohol at reduced pressure and 20.degree. C. to 30.degree. C., a complex product is obtained which when combined with a vinyl containing siloxane polymer has an extended shelf-life but can be cured by heating. The complex product functions as a crosslinker, a catalyst and an inhibitor which retards the reactions of silicon-bonded hydrogen atoms with aliphatic unsaturation catalyzed by platinum.
