DEFINITION

Classification: 204/471

Coating or forming of object:

(under subclass 450) Process directed to the coating of a substrate or the formation of an object by electrophoresis or electro-osmosis.

(1) Note. Electrophoretic forming processes are defined herein as an electrophoretic coating process wherein the coated layer is subsequently removed from the coated substrate.
