DEFINITION

Classification: 264/123

(under subclass 109) Processes which include the step of treating the surface of particulate material and/or a dry adhesive coating previously applied to the particulate material, to render the surface of the material tacky thereby causing bonding of the individual particles to each other.

(1) Note. The particulate material, usually thermo-plastic, is treated with a fluid material which is not an adhesive, per se, and usually is a solvent for the material, or by the application of heat to render tacky the solid particulate material or dry coating thereof.

SEE OR SEARCH THIS CLASS, SUBCLASS:

122, for processes in which plural different solid particles are united, one of which may act as an adhesive and which may or may not retain its particle identity on, for example, application of heat to activate it as an adhesive.
