Abstract
A tire dressing composition is provided that includes at least one silicone fluid having a viscosity of between 40 and 500,000 centiStokes at room temperature. An amine functionalized silicone fluid having a viscosity of between 40 and 500,000 centiStokes at room temperature is also present. A thickener is present to yield a coating from the composition has limited sag, low tack upon coating formation, and desirable durability properties. An organic solvent is present in which the at least one silicone fluid and the amine functionalized silicone fluid are soluble or suspended. A process is provided for dressing a tire having a previous silicone coating thereon, the process including applying the tire dressing composition and allowing a solvent to evaporate from the composition to form a tire dressing coating. The coating producing an initial gloss of great than 200 units. A gloss of greater than 110 units is maintained for at least four weeks subsequent to the application under normal vehicle operation conditions.
