Abstract
A silicone channel sealant with improved solvent and water resistance comprising a diorganopolysiloxane of 50 to 200,000 centipoise viscosity and blends of diorganopolysiloxanes wherein powdered polytetrafluoroethylene, treated and untreated silica filler, a titanate of the formula (RO).sub.4 Ti, where R is selected from alkyl radicals and haloalkyl radicals, and an organic compound containing at least one hydroxy group are present as a water resistance additive. In addition to the above basic ingredients, there can be present in the composition of the present case a silicate, a boron compound, styrene beads, a polyether, and optionally as a corrosion resistant additive such as, zinc chromium salts or iron oxide. The above channel sealant which is desirable as a channel sealant for fuel tanks of aircraft has the advantageous properties that it is both solvent resistant, water resistant, has good consistency and does not flow at low pressures but is easily injectable.
