SCOPE The material defined by these specifications is a one component moisture curing urethane adhesive with a fast fix behavior which is primerless to clearcoat paint chemistries. 2
3、. APPLICATION These specifications were released originally for material used in conjunction with a one or two stage glass priming operation (primers identified per para 4) to bond glass windshields, glass rear windows and quarter windows to painted metal surfaces. These materials will also bond pri
4、merless to e-coated surfaces that are contaminate free and can also be used in conjunction with metal flange primers. Application Temperature: above 55 C 2.1 MANUFACTURING PROCESS RECOMMENDATION These adhesives are moisture sensitive and require special handling for manual and automated process. App
5、roved suppliers are responsible for maintaining the accuracy and relevancy of these process parameters (in their Process Standard). Approved suppliers must submit any changes to these process parameters in a timely manner (within 30 days) for review and approval by Materials Engineering, Vehicle Ope
