DEFINITION

Classification: 427/472

Positioning, orientation, or application of nonsprayed, nonatomized coating material solely by electrostatic charge, field, or force:

(under subclass 458) Processes wherein a coating material, which may be fluid or discrete particles, is caused to move from a container or support surface to a substrate or have its relative alignment or placement influenced by using electrostatic charge, field, or force as the sole or principal source of energy.

(1) Note. Mechanical projection is a form of spraying and thus excluded.

(2) Note. Atomized refers to breaking up a liquid into a fine spray or fog.
