ABSTRACT:
A wipe-on clear protectant based on polyurethane is provided, which provides a finish that is durable and long lasting, is not injurious to the leather or artificial leather on which it is applied, in the instance of use on vinyl, impedes, rather than fosters, plasticizer migration, and is not slippery or tacky to the touch. In the preferred composition, polyurethane is dissolved in isopropyl alcohol, and ethylene glycol monobutyl ether is added, and the resulting liquid is wiped as a clear liquid onto the surface of the cleaned and dry leather or artificial leather produce which is to be protected. The finish dries clear, even, waterproof, smooth and without tackiness in less than thirty minutes.
