Compositions: coating or plastic

SECTION I - CLASS DEFINITION

This class is the broad generic class for:

(1) Coating, impregnating or plastic compositions, especially those which set or harden to retain a given shape. Most of the compositions herein found are those which are capable of undergoing a change from a fluent to a nonfluent condition, or from a solid noncoherent form to a solid coherent form, which changes may be effected in any or more of the followings ways:

(a) By setting, e.g., concrete:

(b) By chemical reaction or conversion, e.g., viscose;

(c) By removal of solvents or vehicles, e.g., lacquers;

(d) By solidification from a molten state, e.g., asphalt or sulfur.

This class takes all such compositions unless more specifically provided for in other main classes, for which see the notes below under the heading "Coating or Plastic Compositions Elsewhere Classified".

The term "coating" is used throughout the definitions and notes of this class to include "impregnating".
