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° F. to 400° F. (about 65° C. to 204° 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.
