US Patent:

8137646, Mar 20, 2012

Filed:

Mar 25, 2008

Appl. No.:

12/054985

Inventors:

Simon Boocock - Liberty Township OH, US

Assignee:

The Shepherd Color Company - Cincinnati OH

International Classification:

C01G 31/02
C01G 25/02

US Classification:

423 62, 106451, 423 71, 4235948, 42359412, 428413, 428416, 428480

Abstract:

A mixture of zirconium hydroxides or zirconium basic carbonate with vanadium oxide (V205) co-reacts in high temperature aqueous slurry to form respectively an amorphous material, believed to be based on a zirconium analog of a zeolite structure, and a solid solution of zirconium oxide with vanadium oxide. The subject compositions, free of hexavalent chromium, are highly effective in providing blister-free corrosion prevention in typical coil and aerospace grade epoxy primer and color coat combinations.

Appl. No.:

12/211390

Inventors:

Simon K. Boocock - Liberty Township OH, US

Assignee:

The Shepherd Color Company - Cincinnati OH

International Classification:

B01J 21/00

US Classification:

106 1405, 423 65, 428615

Abstract:

A mixture of Zinc Oxides or Hydroxides with Aluminum Hydroxides and Vanadium Oxide (VO) co-reacts in high temperature aqueous slurry to form highly crystalline forms of Hydrotalcite, containing the Decavanadate ion as a source of corrosion inhibition. The subject compositions, free of hexavalent chromium, are highly effective in providing blister-free corrosion prevention in typical coil and aerospace grade epoxy primer and color coat combinations.

Appl. No.:

12/211459

Inventors:

Simon K. Boocock - Liberty Township OH, US

Assignee:

SHEPHERD COLOR COMPANY - Cincinnati OH

International Classification:

B32B 15/04
B32B 15/01
C01B 33/26

US Classification:

428639, 428450, 428457, 4233271

Abstract:

Sodalite is synthesized in the presence of a stoichiometric quantity of Permanganate ion. After thorough washing to remove trace salts the resulting pigment may be encapsulated with amorphous silica using the Iler process. The resulting pigment has enhanced acid stability and provides excellent corrosion protection on reactive metal substrates such as Aerospace Aluminum or Coil grade Hot-Dip Galvanized Steel.
