Iron oxide-containing one or two component polyurethane lacquer for the coating of elastomers its production and use

摘要

The invention relates to one- or two-component polyurethane lacquers for coating elastomers containing polyurethane prepolymers with an average of two or more isocyanate groups per molecule which have been prepared by mixing alcohols having a functionality of two or higher with an excess of isocyanate compounds having a functionality of two or higher and solvents, characterized in that a compound containing iron oxide is added in an extremely large quantity to improve surface slip, and to the production and use of such one- or two-component polyurethane lacquers.
