  • Inhibited metal pigment pastes containing molybdate pigments and suitable for aqueous coating compositions
    Patent number: 5993523
    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.

  • Colored metallic pigments
    Patent number: 5558705
    Abstract: 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.
