DEFINITION

Classification: 205/205

Treating substrate prior to coating:

(under subclass 80) Subject matter wherein one or more preliminary preparatory treatments of the substrate to be coated are performed.

(1) Note. For this subclass, and those indented hereunder a substrate is considered to be the object to be coated prior to the execution of any positively recited coating step.

(2) Note. Processes which include the formation of a temporary coating which is completely removed prior to the formation of a permanent coating are included herein.

(3) Note. The preliminary preparatory treatments of the substrate do not result in the deposition of material that remains as part of the finished article.
