An aqueous coating composition which can be applied to a cured rubber surface, such as the white sidewall, colored sidewall, raised white lettering or raised colored lettering of a tire, to provide a protective coating against staining and scuffing. The composition includes (a) polyvinyl alcohol, (b) ethylene-vinyl acetate copolymer, and (c) one or both of (i) a silicon emulsion in an amount sufficient to provide increased scuff resistance to a coating prepared from the composition, and (ii) a thickening agent of a type and in an amount effective to render the composition shear-thinning.

The invention relates to an aqueous polyvinyl alcohol/polyvinyl acetate-based composition which can be applied to a cured rubber surface, such as the white sidewall of a tire, to provide a protective coating against staining and scuffing. Preferably, the aqueous composition includes a polysiloxane agent for increasing the scuff resistance and high humidity resistance.

Recoverable, peelable masking films prepared from an aqueous emulsion of polyvinyl acetate resins are disclosed. The aqueous composition is an admixture about 70 to 80 wt-% an aqueous vehicle; about 20 to 30 wt-% of a polyvinyl acetate film-forming resin; about 0.1 to 5 wt-% of a plasticizer; about 0.1 to 5 wt-% of a water soluble polysaccharide gum; less than about 1 wt-% of an emulsifiable thickening agent; about 0.01 to 1 wt-% of a release agent to render a film formed from the aqueous composition peelable from a substrate; and about 0.1 to 1 wt-% of a defoaming agent. The composition can then be dried to form a peelable film consisting essentially of a single layer comprising about 70 to 99 wt-% of polyvinyl acetate resin; about 0.1 to 15 wt-% a water soluble polysaccharide gum; about 0.1 to 15 wt-% of a emulsifiable thickening agent; and about 0.01 to 5 wt-% of a release agent to render a film formed from an aqueous composition peelable from a substrate. The aqueous, film-forming composition is reformable by adding a sufficient quantity of water to the dried film. In addition, the composition can be formed into a pressure sensitive masking film consisting essentially of a single layer of the film. The film can be formed into rolls of tape or stencil sheets. Also, the film can be packaged for shipment and reformulated by a customer or user by reconstitution with an aqueous vehicle.
