USE OF CLEAR VARNISHES BASED ON ORGANIC POLYISOCYANATES FOR COATING FLAT ARTICLES BASED ON POLYVINYLCHLORIDE

摘要

The present invention relates to a process for coating polyvinyl chloride sheet products, optionally containing plasticizers, with clear coatings which can be hardened under the influence of atmospheric moisture and have a viscosity at 23 DEG C. of from about 60 to 2500 mPa.s, and which contain (a) at least one polyisocyanate which is liquid at room temperature, (b) up to about 15% by weight, based on the coating of solvents, and optionally (c) conventional auxiliary agents and additives, and to the coated products produced therefrom.
