Bicomponent polyurethane coating compositions containing polyester polyols as binder components

摘要

The present invention consists of a binder comprising a polyisocyanate and a) certain polyol mixtures and b) certain polyester polyols having 80 to 250 hydroxyl groups prepared from aliphatic unsaturated dicarboxylic acids and optionally aliphatic saturated dicarboxylic acids. Bicomponent polyurethane coating compositions and their use in the production of coatings on plastic moldings such as those used in automobile production.
