Filed:

Nov 15, 2002

Appl. No.:

10/295455

Inventors:

Renee Kelly - Media PA, US
Arnold Frances - Glen Allen VA, US

International Classification:

C08F006/00

US Classification:

528/501000

Abstract:

The present invention is directed to a process for producing micropulp. The process includes contacting organic fibers with a medium comprising a liquid component and a solid component, agitating the medium and the organic fibers to transform the organic fibers into the micropulp dispersed in the medium. If desired, the slurry of the micropulp in the liquid component can be used or the micropulp can be separated from the medium. The micropulp can be readily incorporated into coating compositions such as those used in automotive OEM or refinish applications. The micropulp can also be incorporated into powder coating applications or as a thixotrope or reinforcement in polymer formulations.

US Classification:

524/035000

Abstract:

The present invention is directed to a process for producing a coating composition having improved chip resistance. The process includes contacting organic fibers with a medium comprising a liquid component and a solid component, agitating the medium and the organic fibers to transform the organic fibers into the micropulp dispersed in the medium, separating the solid component from said medium to form a slurry; and adding the slurry or an aliquot thereof to the coating composition. The coating compositions can be used in automotive OEM or refinish applications as well as in industrial coating applications.
