PCT No. PCT/DE96/00312 Sec. 371 Date Oct. 28, 1996 Sec. 102(e) Date Oct. 28, 1996 PCT Filed Feb. 24, 1996 PCT Pub. No. WO96/26972 PCT Pub. Date Sep. 6, 1996A 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:R1Si (OR')3(I)where R1 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.
