DEFINITION

Classification: 156/308.6

(under subclass 308.2) Subject matter wherein a gaseous or liquid agent is applied to a surface to be bonded to improve the bonding properties of the surface.

(1) Note. Usually the added agent is a solvent which tackifies the surface to be bonded.

(2) Note. The process need not include a step of removing the treating agent.
