Abstract

Methods, treatment compositions and treatment systems for forming a detachable and renewable coating on a receptive surface by a process of applying a treatment composition comprising a plurality of hydrophobically modified fumed silica particles colloidally dispersed in a volatile solvent; allowing the volatile solvent to evaporate; and thereby depositing a protective coating on the receptive surface consisting of a layer of the hydrophobically modified particles. The process provides a coating with dirt- and water-repellency properties that effectively shed dry particulate soils as well as water from the treated receptive surface. The methods, treatment compositions and treatment systems are useful in providing detachable coatings and treated articles featuring surface protective benefits including dirt- and water-repellency, self-cleaning with water, and easier cleaning benefits when applied to a variety of automotive and home surfaces, both interior and exterior.
