US Patent:

44826591, Nov 13, 1984

Filed:

Oct 21, 1983

Appl. No.:

6/544150

Inventors:

Zal N. Sanjana - Verona PA
Joseph R. Marchetti - Greensburg PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

C08G 5942
H01B 340
B29D 302

US Classification:

523414

Abstract:

Disclosed is a water based thermosetting epoxy composition of a water compatible epoxy resin, about 5 to about 35% based on total solids of a water polymerized impact modifier in a water based latex, about 1. 5 to about 7% based on the weight of the epoxy resin of a water compatible epoxy hardener, up to about 0. 3% based on the weight of the epoxy resin of a catalyst, and sufficient water to provide a viscosity of about 100 to about 400 centipoises. The compositions are used to prepare high impact strength, high damping laminates.

Appl. No.:

5/672902

Inventors:

Robert D. Jerabek - Glenshaw PA
Joseph R. Marchetti - Greensburg PA
Robert R. Zwack - New Kensington PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

C08G 5124
C08G 3008

US Classification:

260 292EP

Abstract:

The pH, dispersibility and throw power of amine group-solubilized, epoxy resin-derived, cationic electrodepositable resins can be enhanced by the incorporation of primary amine groups into the resin molecule. The primary amine groups are incorporated by reacting certain polyamine compounds in which the primary amine groups are blocked by ketimine groups into the acid solubilizable, amine group-containing electrodepositable resins derived from epoxy group-containing resins.

Appl. No.:

5/656542

Inventors:

Rostyslaw Dowbenko - Gibsonia PA
Joseph R. Marchetti - Greensburg PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

C08G 5916
C08J 306
C25D 1306

US Classification:

260 292TN

Abstract:

Coating compositions applicable by conventional coating techniques as well as by electrodeposition are provided by reacting an epoxy-containing organic material with a compound containing at least one phenolic hydroxyl group and a group hydrolyzable to a carboxyl group. Examples of such hydrolyzable groups include ester groups, amide groups and nitrile groups. Compounds include esters of benzoic, salicylic and diphenolic acids, and phenolphthalein. The resultant product may then be hydrolyzed and solubilized, using any of the known hydrolyzing agents, e. g. , aqueous potassium hydroxide, aqueous sodium hydroxide and aqueous solutions of the various amines used in the art.

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

C25D 1306

US Classification:

204181

Abstract:

It has been found that aqueous coating compositions comprising a resin containing capped or blocked isocyanate groups, quaternary onium salt groups and, optionally, free epoxy groups may be electrodeposited on a cathode to produce coatings having highly desirable properties.

C08G 5914

US Classification:

260 292EP

Abstract:

Novel, chain-extended adducts formed from reacting high molecular weight polyepoxides and polyester polyols containing at least two alcoholic, primary hydroxyls per molecule are disclosed. The chain-extended polyepoxides are adducted with a secondary amine and made dispersible in water with acid. The water-dispersed resins can be applied to a wide variety of substrates by cationic electrodeposition. When compared to resins which are not chain extended, the resins of the invention have higher rupture voltages, improved film-forming properties and deposit as films with improved flexibility.
