Blends of polyvinyl alcohol and polyurethane water dispersions for increased humidity resistance of water soluble white sidewall paints

摘要

A rubber laminate comprising a rubber substrate having coated thereon a blend of a water dispersible insoluble polyurethane and a water soluble polyvinyl alcohol. The combination of water soluble and water insoluble polymers upon drying result in a film that is humidity resistant, and has good abrasion resistance but can be removed by high-pressure washing or scrubbing.
