DEFINITION

Classification: 156/307.3

With coating or impregnating a face to be adhered:

(under subclass 307.1) Subject matter wherein at least one lamina to be bonded is treated with a material which penetrates the lamina at least in part or which forms a coating on a face to be adhered.

(1) Note. The coating need not be applied as a liquid or particulate solid but may be a gaseous treating agent which reacts with the substance of the lamina to form a so-called "reaction coating".

SEE OR SEARCH THIS CLASS, SUBCLASS:

182, for a process of binding in which an intermediate laminate, (e.g., a coated substrate, etc..), is bonded to another laminate by completing polymerization, e.g., vulcanization, between the intermediate laminates.

278+, for a process in which a nonadherent face of a lamina is coated.
