ABSTRACT:
The method of this invention produces a high strength, one-part fluorosilicone sealant which is stable in the absence of moisture and contains an in situ treated reinforcing silica filler. The fluorosilicone sealant is produced by a process which in situ treats the reinforcing filler with a di(trifluoropropyl)tetramethyldisilazane in the presence of a portion of the fluorosilicone polymer. The remainder of the polymer is then added and the reinforced polymer is admixed with a moisture activated curing system to give a sealant which cures upon exposure to moisture to give an elastomer. The sealant is easily extrudable from a storage container. The cured elastomer has improved tensile strength, tear strength, and elongation values. The cured elastomer, being a fluorosilicone, is resistant to non-polar organic hydrocarbon fluids such as aircraft jet engine fuels and gasoline.
