Abstract
A method of producing a layer which is friction-reducing on an elastomeric substrate includes (a) providing an elastomeric substrate; (b) forming a sol by hydrolysis and condensation of at least one silane having a formula: R.sup.1 Si (OR').sub.3 (I) where R.sup.1 is one of a glycidyloxy-functional residue or a mercapto-functional residue and R' is a residue of a lower alkyl group having 1-4 carbon atoms; (c) coating the elastomeric substrate with the sol to form a coating; and (d) curing the coating to form a gel. The method is particularly suited for the coating of rubber surfaces, e.g., wiper blades.
