METHOD OF PRETREATING AUTOMOTIVE PAINT POWDER FOR USE IN SEALANTS AND COMPOSITION PRODUCED THEREFROM.

摘要

A method of pretreating dried automotive paint powder for use in a sealant or adhesive composition is provided. The method includes heating the automotive paint powder to a temperature between about 150 DEG F. to 400 DEG F. (about 65 DEG C. to 204 DEG C.) to reduce volatile compounds in the powder. The paint powder may then be added to a sealant or adhesive composition which is heated during its manufacture and use without the release of hazardous gases into the manufacturing environment.
