Phosphonic Acid Derivative Treatment Of Metallic Flakes
US Patent:
6863718, Mar 8, 2005
Filed:
Oct 31, 2001
Appl. No.:
10/004486
Inventors:
H. Taylor Lamborn - Shillington PA, US
Robert E. Souerwine - Slatington PA, US

Assignee:
Silberline Manufacturing Co., Inc. - Tamaqua PA
International Classification:
C09D005/08
US Classification:
106 1412, 106 1405, 106 1444, 106403, 106404, 428470
Abstract:
Metal pigment particles are treated with a product resulting from the reaction between an organic phosphonic acid with an amine having at least one organic group containing at least six carbon atoms to inhibit their reactivity to water. The treated metal particles can be used in coating and ink compositions. Additionally, the treated metal particles can be used to formulate pastes and dispersions that are provided to a coatings manufacturer.

US Patent:
5993523, Nov 30, 1999
Filed:
Jun 5, 1998
Appl. No.:
9/092385

Silberline Manufacturing Co., Inc. - Tamaqua PA
International Classification:
C09D 162
US Classification:
106 1421
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.
