5、G330-A2/A3/A4) heat curing and E-coatable, structural metal-to-metal adhesives. The version A4 contains glassbeads for improved hemflange-filling rate. 2. APPLICATION These specifications were released originally for material used for structural bonding of metal-to-metal body components such as the
6、inner and outer panels (hem flange) of doors, hoods, and deck lids, etc. These adhesives can be used to bond cold rolled as well as precoated metal substrates. The materials are applicable on oiled surfaces with acceptable oil film weights (European applications limit the oil/pre-lubricant film weig
7、ht to max 3 g/m, see Performance Spec. WSK-M11P47 para. 3.6). Note: Care must be taken to ensure that the local oil film weight in the area of the adhesive/sealer application does not exceed the critical limit. Monitoring of the film thickness, adequate storage of the part and/or cleaning of the sur
8、face prior to sealer/adhesive application is necessary to avoid critical film thickness values, which would then cause malfunction of the sealer/adhesive. Adhesive handling strength is obtained after induction heating to adhesive temperature of 185 C for 5 seconds. 3. REQUIREMENTS 3.0 STANDARD REQUI
