Abstract
The present invention relates to an encapsulated glazing, a priming composition for treating a glazing, and a process for the adhesion of a thermoplastic profile to a glazing. The process consists of treating at least the area of the glazing to be covered with the profile with an organosilane and a composition based on a chlorinated polyolefin, the average molecular weight of which is between 1,000 and 300,000 (as determined by gel permeation chromatography), followed by encapsulating the treated glazing with a thermoplastic material, in order to form the profile. Preferably, the encapsulating step is performed by injecting.
