BK Giulini GmbH has received a patent for a method of manufacturing an anticorrosive pigment for a zinc-free coating composition comprised of an anticorrosive pigment wherein the anticorrosive pigment consists of aluminum orthophosphate. The method is comprised of the steps of converting an aluminum salt with phosphoric acid or a phosphate in the aqueous phase; and precipitation of aluminum orthophosphate; filtration of aluminum orthophosphate; and drying of aluminum orthophosphate; tempering the orthophosphate at a temperature ranging from 500-800[degrees]C.; and grinding the aluminum orthophosphate, in one step, to a grain size of D50<15 pm and D90<30 pm.
