Encapsulated window ready for mounting and fabrication method therefor
First Claim
1. A one-piece or laminated window fitted with a peripheral duplicate molded profile ready for mounting by adhesive bonding in a bay, wherein the surface of the peripheral profile intended to be bonded is coated with a polymerized layer obtained from a composition which comprises an isocyanate constituent and a polyalcohol constituent present in excess in relation to the isocyanate constituent in order to form, after polymerization, a polyurethane layer having free hydroxyl groups capable of reacting subsequently with the adhesive strip used to mount the window, wherein the polyalcohol constituent contains at least one polyvinylchloride copolymer containing free hydroxyl groups, wherein the ratio of NCO groups to OH groups of the composition ranges between about 0.30 and 0.99.
