A method of providing a protective coating to a surface, comprising (i) applying to the surface a composition comprising dispersed in an organic solvent (a) at least one hydrolysable silane corresponding to the formula Q n SiG 4-n wherein Q represents a hydrocarbon group that can optionally be substituted, G represents a hydrolysable group and n is 0, 1 or 2; (b) at least one polymer A comprising a polysiloxane segment and having a plurality of -SiY functional groups wherein Y represents a hydrolysable group and wherein the amount of hydrolyzable groups Y bonded to Si atoms is on average more than 6 per polymer; or a condensation product of a hydrolysation reaction of (a) or (b) or (a) and (b) with the proviso that the reaction product is such that not all hydrolysable groups have been consumed, (ii) heat-curing the composition, wherein the surface is selected from one of the following or combinations thereof: engineered wood, steel, aluminum other than aluminum wheel rims, glass, ceramics, polymeric material comprising at least one polycarbonate, polyacrylate, polymethacrylate, polyester, polyamide, copolymers thereof or combinations thereof and wherein the polymer A corresponds to the general formula: (Y 3 Si-) n L'-P-L"(-SiY' 3) m wherein each Y and Y' is independently selected from alkoxy, aryloxy, acyloxy and halogens, n and m represent, independently from each other integers of 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 wherein the sum of n and m is at least 2, preferably 4 or at least 4, P represents the polysiloxane segments and L' and L" may be identical or different groups linking the silane residues -SiY 3 and SiY' 3 with the polysiloxane segment. (i) applying to the surface a composition comprising dispersed in an organic solvent (a) at least one hydrolysable silane corresponding to the formula Q n SiG 4-n wherein Q represents a hydrocarbon group that can optionally be substituted, G represents a hydrolysable group and n is 0, 1 or 2; (b) at least one polymer A comprising a polysiloxane segment and having a plurality of -SiY functional groups wherein Y represents a hydrolysable group and wherein the amount of hydrolyzable groups Y bonded to Si atoms is on average more than 6 per polymer; or a condensation product of a hydrolysation reaction of (a) or (b) or (a) and (b) with the proviso that the reaction product is such that not all hydrolysable groups have been consumed, (a) at least one hydrolysable silane corresponding to the formula Q n SiG 4-n wherein Q represents a hydrocarbon group that can optionally be substituted, G represents a hydrolysable group and n is 0, 1 or 2; (b) at least one polymer A comprising a polysiloxane segment and having a plurality of -SiY functional groups wherein Y represents a hydrolysable group and wherein the amount of hydrolyzable groups Y bonded to Si atoms is on average more than 6 per polymer; or a condensation product of a hydrolysation reaction of (a) or (b) or (a) and (b) with the proviso that the reaction product is such that not all hydrolysable groups have been consumed, (ii) heat-curing the composition, engineered wood, steel, aluminum other than aluminum wheel rims, glass, ceramics, polymeric material comprising at least one polycarbonate, polyacrylate, polymethacrylate, polyester, polyamide, copolymers thereof or combinations thereof and wherein the polymer A corresponds to the general formula: (Y 3 Si-) n L'-P-L"(-SiY' 3) m wherein each Y and Y' is independently selected from alkoxy, aryloxy, acyloxy and halogens, n and m represent, independently from each other integers of 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 wherein the sum of n and m is at least 2, preferably 4 or at least 4, P represents the polysiloxane segments and L' and L" may be identical or different groups linking the silane residues -SiY 3 and SiY' 3 with the polysiloxane segment.
