DEFINITION

Classification: 508/138

With non-siliceous fluorine-containing polymer as additional component or surface-treating agent (e.g., polytetrafluoroethylene, etc.):

(under subclass 136) Compositions which contain, in addition to the silicon dioxide, silicic acid, orthosilicate, or metasilicate, a polymer that contains fluorine but does not contain silicon; the polymer may be present as an additional component or as a surface-treating agent for the silicon dioxide, silicic acid, orthosilicate, or metasilicate.

(1) Note. An example of a component provided for herein is polytetrafluoroethylene.
