  • Coating composition comprising calcium hydrogen-phosphate, processes for preparing it, its use and substrates coated with it
    Patent number: 9080002
    Abstract: The abstract concerns a coating composition comprising 25-55% by weight of one or more film formers, 2.5-55% by weight of one or more fillers, 0-10% by weight of one or more additives, and 0-30% by weight of a solvent, based on the total weight of the coating composition. As the filler or a filler the composition comprises calcium hydrogen phosphate in a mass fraction of 2.5-20%, preferably 5-15%, more preferably 7.5-11% by weight based on the total weight of the coating composition. The invention further concerns processes for preparing this coating composition, its use as a coating material in the vehicle sector, and substrates produced therewith.
