Class 516: Colloid Systems And Wetting Agents; Subcombinations Thereof; Processes Of Making, Stabilizing, Breaking, Or InhibitingSubject matter provided for in this class: colloid systems (also called colloid dispersions or colloid suspensions) of the following six systems (dispersed phase/continuous phase): solid/liquid; solid/gas; liquid+/solid; liquid/liquid; liquid/gas; gas/liquid (+liquid in gels may be dispersed or continuous in the continuous solid phase); wetting agents (compositions for wetting surfaces, including spreading, penetrating, or leveling); subcombination compositions of colloid systems or wetting agents containing at least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems or in wetting agents, which includes: (a) compositions fully compounded for and intended to be made into a colloid system, such as an assemblage of compounds merely requiring non-material input (such as agitation) to effect a colloid system; (b) compositions consisting of a potential dispersand* combined with a colloid system making or stabilizing agent; (c) compositions consisting of a mixture of colloid system making or stabilizing agents, or, of one such agent* and an adjuvant*, or, of a mixture of adjuvants, in each instance the composition lacking both the material to be dispersed and the material in which it is to be dispersed, including thickening, suspending, stabilizing agents, or protective colloid compositions.
Subclass 100: The organic material coats, impregnates, or surface modifies solid inorganic material (e.g., dextrin modified clay)

Class 264: Plastic And Nonmetallic Article Shaping Or Treating: ProcessesProcesses for molding, casting, or shaping of nonmetallic materials to produce articles. Liquid or melt comminuting of materials other than glass or metal. Uniting or compacting of bulk or randomly assembled particles. Furnace Lining or repair. Melt shaping in the absence of a mold or shaping surface, e.g., spheroidizing of particles. Working or treatment of nonmetallic materials not otherwise provided for.
Subclass 7: Coated particles
Class 428: Stock Material Or Miscellaneous ArticlesThis is the residual class for: 1. Stock material in the form of a structurally defined web, sheet, rod, strand, fiber, filament, cell, flake, particle not provided elsewhere. 2. Stock material in the form of a web, sheet, mass or layer which consists of or contains a structurally defined constituent or element. 3. A nonstructural laminate defined merely in terms of the composition of one or more layers. 4. An article of manufacture or an intermediate-article not provided for elsewhere. 5. A process for applying an impregnating material to a naturally solid product such as a wood beam, a sheet of leather or a stone, or for applying a coating to a base, and which process includes no significant method step.
Subclass 407: Including synthetic resin or polymer
Class 524: Synthetic Resins Or Natural Rubbers -- Part Of The Class 520 SeriesPart of the Class 520 Series - some general types of subject matter include: Solid synthetic resins, per se, regardless of utility; processes of preparing a synthetic resin involving a chemical reaction; reactable compositions which form a product; processes of purifying a solid synthetic resin or composition containing a synthetic resin by a chemical or physical process; process of reclaiming or recovering a solid synthetic resin; processes of treating a synthetic resin or specified intermediate condensation product with a reactant, or product thereof; blends of solid synthetic resins, processes of preparing or treating such blends; chemically reacted solid synthetic resins or processes of preparing; potentially reactable compositions which contain a solid synthetic resin or SICP and products of such a reaction, or processes of preparing; room vulcanizable potentially reactive compositions which merely require moisture and which are usually activated by heat and/or pressure to form a product; compositions of a nonreactant material and a solid synthetic resin or SICP; compositions containing a structurally defined material which is dispersed in a matrix which is not identified by overall dimension or some structure or processes of preparing; single-layered products containing a solid synthetic resin or composition thereof reciting no structure or dimension, or a fiber, filament, etc., which is no more than the material from which it is made, nonstructured single-layered web or sheet is encompassed; particles or a powder, per se, of a solid synthetic resin or composition thereof for which particles or powder no dimensions are recited; reactable compositions which form a product proper for this class and contain a photoinitiator or photosensitizer which are activated by wave energy or processes of preparing.
Subclass 588: From silicon-containing reactant
