ABSTRACT:
A material especially adapted for incorporation in a coating composition, for example, as a secondary pigment, and characterized in having corrosion inhibiting properties. The material consists of finely particulate material on which is coated a film of fatty amine or fatty amine salt. The material coated on the particles is characterized in having a high area to volume ratio and the properties thereof in respect of inhibiting corrosion are thereby enhanced. The particulate material is advantageously natural crystalline calcium carbonate.
