(under the class definition) Compositions which contains a mixture or association of two or more reactants chosen for subsequent and not immediate chemical interaction thereof, i.e., vis-a-vis, substances peculiar thereto, and processes of making the same.
(1) Note. This subclass provides for the addition of a stabilizer or inhibitor to a composition to prevent the interaction between two or more reactants such that the reactants con interact subsequently upon removal or interruption of the stabilizer or inhibitor or otherwise render them reactive.
(2) Note. This subclass does not take solid synthetic polymers as part of a composition.
(3) Note. A composition containing potentially reactable ingredients which are to be polymerized and which contains
all of the necessary reactants to form the desired solid synthetic resin; or contains those reactants which are potentially reactable at room temperature or requiring merely the addition of heat, pressure, or moisture when said reactants contain a Si-C, Si-H bond or -N=C=X group (wherein x is a chalcogen atom); or contains a liquid polysulfide is classified in appropriate polymer classes.

428, Stock Material or Miscellaneous Articles,
402+, for solid polymer reactants A and B microencapsulated within a given microcapsule or a sphere or specified dimensions, and wherein the two are stabilized for subsequent reaction. 516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art; including those instances when a composition would otherwise be proper for this subclass (183.11) and its indented subclasses.
520, Synthetic Resins or Natural Rubbers, appropriate subclasses for a composition containing a solid polymer admixed with a reactant, which may be an additional solid polymer.
