    Abstract: A surface finish composition including a silica-bonded reversibly cross-linked co-polymer and a water-dispersible polyurethane. The silica-bonded reversibly cross-linked co-polymer includes a base co-polymer including monomers derived from one or more ethylenic polymerizable monomers and an alkoxysilyl acrylate; a reversible cross-linking agent; and a silica nanoparticle bonded to the base co-polymer. The amount of water-dispersible polyurethane is 15-50% by weight of the combined amount of water-dispersible polyurethane and base co-polymer.
