DEFINITION

Classification: 427/299

(under the class definition) Processes wherein prior to applying a coating, steps are taken to chemically or physically modify the base.

(1) Note. "Base" is meant to be an uncoated substrate. Pretreating the first coating prior to applying the second coating is not provided for here. Such treating is considered a post-treatment.

(2) Note. Included herein are such operations as washing, cleaning, drying, compressing, heating, etc.

(3) Note. Processes limited to etching for making a base move compatible with or adherent to the coating, wherein the base is the substrate (work) onto which a coating is applied are included.
