Abstract
The present invention provides a method for covering a substrate, and includes the following operations: (a) admixing at least four different silane monomers and at least one bi-silane to a first solvent(s) to form a mixture, with the proviso that at least one of the silane monomers or the bi-silane comprises an active group capable of achieving cross-linking to adjacent siloxane polymer chains of the siloxane polymer composition; (b) subjecting the mixture to an acid treatment so that the silane monomers are at least partially hydrolysed, and the hydrolysed silane monomers, the silane monomers and the bi-silane are at least partially polymerized and cross-linked; (c) optionally changing the first solvent to a second solvent; and (d) subjecting the mixture to further cross-linking of the siloxane polymer to achieve a predetermined degree of cross-linking, depositing the siloxane polymer composition on the substrate, and optionally curing the deposited siloxane polymer composition.
