DEFINITION

Classification: 427/337

(under subclass 331) Processes in which a coating is treated with a chemical agent to modify the coating.

(1) Note. Chemical agents which themselves form a permanent coating are not considered treating agents.

(2) Note. Utilizing a specific atmosphere to prevent a coating from undergoing a change; e.g., reducing to prevent oxidation, is not considered treating.

(3) Note. This subclass provides for applying a first material and thereafter applying a second material which reacts with the first material to form a coating.
