DEFINITION

Classification: 427/483

Utilizing apparatus to atomize and electrostatically charge liquid coating material (e.g., charging electrode adjacent spray source, etc.):

(under subclass 475) Processes wherein an electrostatic charge, field, or force is used to assist in causing a liquid material to be reduced to small particles or fine droplets and deposited on a substrate.

(1) Note. In this subclass processes may be found wherein a charging electrode stationed adjacent the spray source or coating projector causes the coating liquid to be charged and reduced to fine liquid particles.
