Filed:

Feb 14, 2000

Appl. No.:

09/503968

Inventors:

Shiow-Ching Lin - Lawrenceville NJ
Michelle Kelly - Mantua NJ
Bradley Kent - Sicklerville NJ

Assignee:

Ausimont USA, Inc. - Thorofare NJ

International Classification:

C08J 316

US Classification:

523335, 524422, 524429, 524904, 524567, 525934, 427458, 427459

Abstract:

A process for making a PVDF-based powder coating compositions using a co-coagulation process and compositions comprising co-coagulated PVDF, co-coagulated PVDF-based powder coating compositions and substances coated with these compositions. Vinylidene fluoride polymer latex compositions are mixed with compatible thermoplastic polymer latex, such as acrylic polymer latex, and a coagulant is added. The coagulant precipitates the vinylidene fluoride and polymer, and the precipitant is filtered and dried forming the powder coating. The powder coating is homogenous. The coating comprises no solvents and can be applied to a number of substrates.

US Classification:

523332, 523335, 524567, 524904, 525934, 528487, 528488

Abstract:

A process for making pigmented PVDF-based powder coatings by coagulation and powder based coatings made by the process. The process involves blending a PVDF latex and a water reducible acrylic polymer and pigment dispersion, adding coagulant to precipitate solid PVDF and pigment associated by ionic interaction with acrylic polymer binder, separating solids and drying the precipitate. Also, methods for coating substrates with the powder coating and coated substrates.
