DEFINITION

Classification: 427/226

(under the class definition) Processes wherein a coating which is on the base is decomposed by heat or wherein part of

a base is decomposed by heat.

(1) Note. This and indented subclasses exclude heat decomposition of a vapor or gas to form a coating.

(2) Note. This and indented subclasses include carbonization of a substrate or coating or heat decomposition of a material in a coating such as a temporary binder.

223+, for heat decomposition produced by flame contact.

246, for coagulating a coating to form a microporous product. 248.1+, for heat decomposition of a vapor or gas to form a coating.

314+, for a process which includes preheating a base and then applying a coating composition which is decomposed simultaneously with application.

372.2+, for heat treatment of a coating without decomposition, for instance to evaporate a solvent or polymerize a resin.
