Abstract:
1. A method of forming a detachable and renewable protective coating on a receptive surface comprising the steps of: (a) applying a treatment composition to said receptive surface, said treatment composition comprising a plurality of hydrophobically modified fumed silica particles colloidally dispersed in a volatile solvent; (b) allowing said volatile solvent to evaporate from said receptive surface; and (c) thereby depositing said protective coating on said receptive surface, wherein said protective coating provides dirt- and water-repellency to said receptive surface; wherein the protective coating comprises a non-smooth coating on the receptive surface at least after the treatment composition has been applied to the receptive surface and has substantially dried or set, and wherein said non-smooth coating on the receptive surface includes valleys and peaks and an average height between the valleys and peaks of about 1-2500 nm.
