US Patent:

7468401, Dec 23, 2008

Filed:

Feb 18, 2005

Appl. No.:

11/060824

Inventors:

Joseph M. Ferencz - Litchfield OH, US

Assignee:

PPG Industries Ohio, Inc. - Cleveland OH

International Classification:

C09D 5/29

US Classification:

523171

Abstract:

A method of producing a coating composition containing flake-like, color effect pigment particles and polymeric binder. The pigment composition has an initial size with fine particles. Upon mixing and heating the pigment composition to a temperature to achieve a second particle size distribution, the fine particles in the initial particle size distribution are bound to the larger particles in the pigment composition. The time and temperature of bonding the pigment composition can be adjusted to account for the chemistry of the polymeric binder and the loading of the flake-like, color effect pigment.

US Classification:

26421121, 264 406, 264211, 26421123, 26421124

Abstract:

An extrusion process for manufacturing powder coating compositions is disclosed. The process generally includes a shear mixing step done at ambient temperature and a focused heating step in which the shear mix is heated to a higher temperature for a shorter time than in conventional methods. The focused heating provides for a shorter heat history, resulting in enhanced coating properties. The mixture may be cooled before it leaves the extruder.

US Classification:

264040700, 264211000, 264078000

Abstract:

An extrusion process for manufacturing thermosetting powder coating compositions is disclosed. A base material is fed to an extruder body such as from a pre-mix hopper; in one embodiment, hard to incorporate additives, such as pigments, are added to the base material after they exit from the pre-mix hopper and before they exit from the extruder body. In another embodiment, hard to incorporate additives in a dried form are added with the base material. The combined base material and hard to incorporate additives are mixed through at least a portion of the extruder body to form a homogeneous thermosetting powder coating composition. The output of the extruder body may be monitored for composition accuracy, wherein the amount of hard to incorporate additives added is dynamically adjusted based upon the monitored output. The process may be repeated for thermosetting powder coating compositions having distinct hard to incorporate additives utilizing a common base material in the pre-mix hopper. Use of one or more hyperdispersed pigments in the formation of a powder coating is also disclosed.
