Abstract
Metal particles useful for coating compositions, particularly aqueous coating compositions, are produced by treating the metal particles with a molybdate pigment. The molybdate pigment reacts with the surface of the metal particles. The molybdate pigment may be a salt such as a molybdate, phosphomolybdate or silicomolybdate salt, and the salt may include a multivalent cation such as calcium, strontium, barium, magnesium, zinc and aluminum. The metal particles show improved resistance to attack by water.
