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.

Inhibited metal pigment pastes containing molybdate pigments and

The invention relates to a colored pigment comprising a plurality of metallic or mica flakes with a plurality of polymer encapsulated pigment particles adhered to the individual flakes. The colored pigments are useful for imparting color and metallic luster to surface coatings.

Colored metallic pigments

Aqueous resistant metal pigment-containing paste and method for making

A colored metallic pigment composition includes metallic particles which have been treated with a mixture of pigment particles and wax. A polymeric shell is formed on the treated metal particles by means of an organometallic coupling agent. The coupling agent includes a readily-hydrolyzable group which is capable of binding to the metal particle surface, and a relatively non-hydrolyzable group which serves as a binding site for the polymeric shell.

Water resistant metal pigment particles

Metal pigment particles which are treated with both a heteropoly anion compound and a phosphosilicate pigment compound show increased stability against attack by water. The particles are especially useful in aqueous coating compositions.
