US Patent:

39323498, Jan 13, 1976

Filed:

Sep 16, 1974

Appl. No.:

5/506489

Inventors:

Melville J. Camelon - Utica MI
Rodney C. Gibeau - Mount Clemens MI

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

C08K 308
C08K 904
C08K 910

US Classification:

260 4214

Abstract:

Improved powder paint compositions providing greater depth variation of metal pigment particles comprise (1) aluminum flakes individually encapsulated in a thin, continuous, thermoplastic, organic film-former containing an ammonium salt selected from tetraalkyl ammonium halides and substituted tetraalkylammonium halides wherein at least one alkyl radical is replaced with an aryl, phenoxy, or alkoxy radical and (2) a particulate, organic film-former. The encapsulated aluminum flakes are prepared by intimately dispersing the aluminum flakes in a solution of the thermoplastic, organic film-former and the ammonium salt in a volatile solvent and spray drying the resultant dispersion. In the preferred embodiment, the particulate, organic film-former is also a thermoplastic material and, in the most preferred embodiment, it is of the same composition as the coating on the aluminum flakes.

International Classification:

C08K 308
C08K 904
C08K 910

US Classification:

260 17R

Abstract:

Improved powder paint compositions employing particulate metal color producing components comprise a unique combination of (a) aluminum flakes individually encapsulated in a thin, thermoplastic organic film-former (b) nickel powder, and (c) the principal film-former of the powder paint composition in particulate form. The encapsulated aluminum flake is prepared by intimately dispersing the aluminum flake in a solution of the thermoplastic, organic film-former of controlled concentration and spray drying the resultant dispersion. In the preferred embodiment, the principal film-former of the powder paint composition is also a thermoplastic material and, in the most preferred embodiment, it is also of the same composition as the principal film-former of the powder coating composition.

Appl. No.:

5/506486

Inventors:

Melville J. Camelon - Utica MI

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

C08K 308
C08K 904
C08K 910

US Classification:

260 4214

Abstract:

Metal particles used as color producing component in powder coating compositions are individually encapsulated in a thin and continuous coating of thermosettable, organic film-former prior to mixing with the particulate, organic, material which serves as the principal film-former of the powder coating composition. The coated particles are prepared by spray drying a solution of a controlled amount of the thermosettable material in a volatile solvent in which the metal has been dispersed. In the preferred embodiment, the coating thus achieved on the metal particles is cross-linkable with the principal film-former of the powder coating composition.

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

B05D 138
B05D 714
B05D 724

US Classification:

428220

Abstract:

A method for painting automobiles and other articles of manufacture which admits of the use of medium to high concentration of metal pigments, can provide high gloss finish coatings and employs a low concentration of volatile solvents comprising application of a relatively thin, highly pigmented, water-based coating to a substrate, heat curing, application of an unpigmented or lightly pigmented powder coating that is transparent on curing, and heat curing of the powder coating. Products bearing unique finish coatings prepared by this method are claimed. This invention relates to the art of coating. More specifically, this invention relates to a novel method of coating substrates, particularly metal substrates, and to the products produced by such method.
