Janitschke FoE Controlled document at www.MATS Copyright 2016, Ford Global Technologies, LLC Page 1 of 7 PERFORMANCE, DIRECT GLAZING ADHESIVE, WSS-M11P67-A1 ONE COMPONENT, POLYURETHANE 1. SCOPE This specificatio

2、n defined the performance requirement of a one component urethane adhesive which is primerless to clear coat paint chemistries, to clear glass and to ceramic frit qualities. 2. APPLICATION This specification was released for material used to bond primerless glass windshields, glass rear windows and

3、quarter windows to painted metal surfaces. These materials will bond primerless to clear coat paint qualities, to e-coated surfaces that are contaminate free and can also be used in conjunction with metal flange primers or glass primers. 3.
