Patent ID: 8663741

Claim:
Method of treatment comprising (i) applying a treatment composition to at least a portion of the surface of a wheel rim and (ii) allowing a thus applied treatment composition to cure, said treatment composition comprising dissolved or dispersed in an organic solvent: (a) at least one polymer comprising a segment selected from a polysiloxane segment or a fluorinated segment, said polymer having at least one —SiY functional group wherein Y represents a hydrolysable group and wherein said —SiY group is comprised in end groups of the polymer and/or side groups of said polymer, wherein said polymer is a polysiloxane based polymer comprising repeating units of the formula —(R) 2 SiO—, wherein R represents an alkyl group of 1 to 4 carbon atoms or an aryl group; and (b) at least one hydrolysable silane corresponding to the formula (I) or hydrolysates or condensates thereof: Q n SiG 4-n (I) wherein Q represents a hydrocarbon group that can optionally be substituted, G represents a hydrolysable group and n is 0, 1 or 2; or as an alternative to or in addition to components (a) and (b), (c) condensation products of (i) said polymer and (ii) said hydrolysable silane according to formula (I) or hydrolysates or condensates of said hydrolysable silane according to formula (I).
