Summary: | A curable silicone composition is provided that includes a silanol functional silicone fluid. A crosslinker reactive with the silanol functional silicone fluid is combined with the silanol fluid to yield a capped reactive silanol fluid. The composition is provided with a propellant in an aerosol container under pressure so as to expel the capped reactive silanol fluid along with a diluent such as a nonvolatile unreactive silicone, an organic plasticizer, a volatile organic solvent, or a combination thereof. A film produced from this composition provides a plastic or rubber substrate with a high gloss finish with desirable wear properties. The inclusion of the optional diluent and the optional propellant facilitates aerosol application of the curable silicone composition as a thin film coating. An additional attribute of a curable silicone composition as described herein is that a silicone coating cures from the capped reactive silanol fluid in ambient air at 20° Celsius in 60 minutes or less and is independent of cure catalysts that contain tin, titanate, zirconate or amine. A resultant coating is applied to the sidewall of a vehicle tire as an aesthetic and protectorant. |
