DEFINITION

Classification: 427/180

(under the class definition) Processes wherein the coating material is in the form of small discrete pieces.

(1) Note. Included herein are powder, granules, fibers pellets, beads, flakes, and platelets, etc.

(2) Note. The particles may form the coating, or become part of a coating as when applied over a layer of adhesive.

(3) Note. For classification here the particles must not be in solution or in suspension in a liquid or paste while being applied.
