2、indow modules to painted substrates. The modules must be attachedto the vehicle with mechanical fasteners or a permanent adhesive.2. APPLICATIONThis specification was released originally for sealing of quarter windowmodules from water leaks. The materials covered by this specification arefor sealing

3、 only and not as the primary method of attachment. Performancerequirements specified shall apply to, but not limited to, the followingtypes of sealers: foam core tapes, solid elastomeric (typically butyl)tapes, and mechanically foamed materials.This specification does not describe individual materia

4、l properties. Theapplicable matertial specification should be referenced for non-performancecharacteristics.Compliance with this performance specification does not guarantee thesealer will function for all potential applications on a vehicle. Thespecific design condition should be evaluated by a pla
