To solve the problem of lower scratch resistance of matte black PU coatings， according to the characteristics and quality demand for automotive interior parts coatings，an excellent anti-scratch single-coat matte black PU coatings for automotive interior parts was developed by selection of different hydroxy acrylic resins，suitable additives and optimized formulation design，which was formulated with a blended binder of medium hydroxyl value acrylic resin，and a specific functional resin and mixed with matting agents，magnesium powder，wax etc.The overall performance of the new coatings was tested.The results showed that the matte black PU coatings developed provided better comprehensive performance， especially the scratch resistance. It could be scaled up for further applications for automotive interior parts.
