Flameproofing Composition

US Patent:

47418656, May 3, 1988
Filed:

May 7, 1986
Appl. No.:

6/860739
Inventors:

Donald P. Kintz - Westford MA
Stephen N. Davis - Cleveland NC
Assignee:

Nyacol Products, Inc. - Ashland MA
International Classification:

C09K 2100
C08K 310
C07C 1742
US Classification:

252609
Abstract:

Polymer systems can be rendered flame retardant by adding a source of halogen and particles of antimony pentoxide that have been dried from colloidal dispersions that have been treated with certain metal ions. The properties of the polymer are conserved when the colloidal dispersion is treated with ions of metals that have insoluble antimonates before drying to form a powder.

US Patent:

51820480, Jan 26, 1993
Filed:

Sep 30, 1991
Appl. No.:

7/767482
Inventors:

Donald P. Kintz - Westford MA
David L. Catone - Hopkinton MA
Assignee:

Nyacol Products Inc. - Ashland MA
International Classification:

B01F 312
C09K 2104
C09K 2100
US Classification:

2523635
Abstract:

Disclosed are a novel class of colloidal antimony pentoxide powders having improved dispersibility in polar solvents; and novel processes for preparing same, which processes include the initial step of preparing a new intermediate consisting of an antimony pentoxide/phosphoric acid sol containing at least 35% by weight of antimony pentoxide based upon the total weight of the sol.

US Patent:

53067428, Apr 26, 1994
Filed:

Dec 26, 1991
Appl. No.:

7/813458
Inventors:

Donald P. Kintz - Westford MA
Assignee:

Nyacol Products Inc. - Ashland MA
International Classification:

C08K 902
US Classification:

523200
Abstract:

Disclosed are novel antimony oxide flame retardant dispersions containing trivalent antimony deposited on the surface of antimony pentoxide particles, which compositions are particularly useful for providing flame retardancy to fiberglass products.

US Patent:

42858461, Aug 25, 1981
Filed:

Apr 28, 1980
Appl. No.:

6/144345
Inventors:

John F. Hardy - Andover MA
Donald P. Kintz - Westford MA
Vaughn W. Taylor - Lynn MA
Assignee:

Cabot Corporation - Boston MA
International Classification:

C08L 6702
C08L 6300
US Classification:

260 292E
Abstract:

Disclosed herein are flatted water-reducible coating compositions of the varnish, paint or enamel types, which compositions comprise a water-miscible film forming resin, water as the predominant solvent and a particulate finely-divided silica flatting agent. The method of the invention involves the initial production of a mill paste formulation containing the film forming resin followed by a let-down step employing water as the predominant solvent. The silica flatting agent is introduced into the composition as an aqueous dispersion thereof during or after said let-down step.
