DEFINITION

Classification: 204/510

With pretreatment of substrate (e.g., cleaning, wetting, etc.):

(under subclass 471) Process in which the substrate is treated to prepare it for coating (e.g., cleaning, wetting, etc.).

(1) Note. Placement in this subclass requires positive recitation of one or more pretreatment steps and does not provide for the mere use of a substrate which was previously made or treated by an unrecited method.
