DEFINITION
Classification: 29/424
Temporary protective coating, impregnation or cast layer:
(under subclass 423) Process in which the separate material associated with the part is in the nature of a coating, impregnation, or cast layer.
(1) Note. The coating is usually for the purpose of protecting or supporting the coated surface during treating or shaping.
(2) Note. The terms "coating", "impregnation", and "cast layer" as used in this definition are defined in the class definition of Class 118, Coating Apparatus, sections II and VII, and are as follows: "the term coating is used throughout the definition in a generic sense and could mean either (1) an initially fluent film or layer of material lying on or bonded to the surface of a base, or (2) an impregnating material which penetrates the base either partially or completely and all or part of which is retained therein, either in its original form or physically or chemically combined therewith". Casting includes applying a layer of material on a base, in which the layer of such thickness as to require molds, walls, or flanges on the base to retain the cast material thereon.
