Abstract

A method for processing compositions, compositions obtained by such a process and methods of use are disclosed for forming a detachable and renewable protective coating which is substantially transparent. The inventive process compositions are produced by making a highly concentrated dispersion of hydrophobically modified silica particles in the presence of an optional, yet preferable, disilazane derivative under high shear conditions. These process compositions are intended to be further diluted to final treatment compositions, optionally while adding other functional ingredients.
