DEFINITION

Classification: 204/504

And separate crosslinking or curing agent:

(under subclass 502) Process in which the bath used for coating also contains a separate compound or element intended to enhance crosslinking or curing of the coating.

(1) Note. For the purposes of this subclass and the subclass indented hereunder, the presence of a separate crosslinking or curing agent (i.e., not chemically bound to a

composition to be coated) must be positively recited.

SEE OR SEARCH THIS CLASS, SUBCLASS:

506, for other cathodic electrophoretic or electro-osmotic coating processes using a bath containing a separate crosslinking or curing agent.
