5、SCOPE The materials defined by these specifications are solvent free, spot weldable adhesives and sealers. 2. APPLICATION These specifications were released originally for materials used to bond sheet metal body parts. The materials are applicable on oiled surfaces with acceptable oil film weights (
6、European applications limit the oil/pre-lubricant film weight to max 3 g/m, see para. 3.20). 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
7、part and/or cleaning of the surface prior to sealer/adhesive application is necessary to avoid critical film thickness values, which would then cause malfunction of the sealer/adhesive.

32、 (European Applications) All materials released to this specification must be applicable to oiled surfaces, including corrosion protection oil, wash oils, pre-lubricants, draw oils, hot melts etc. The approved products for use in Ford of Europe or the European brands are listed in the applicable app
33、roved source list (contact materials engineering for details). The supplier must confirm the compatibility of the adhesive/sealer material to these specific coating materials in the appropriate lab tests listed in para 3 and - prior to vehicle production - in a line trial in cooperation with Ford ma
34、nufacturing engineering. The lab test panels must be oiled with maximum permissible oil film thickness (see FLTM BZ 150-11 Oiling of Steel Surfaces). Reference oil for adhesive performance comparison is Fuchs Anticorit RP 4107S Attention: New compatibility tests are necessary if the oil grade of the
35、 affected part is changed! Nominal oil film weight is: 1 - 1.5 g/m The maximum permissible oil weight for full adhesive performance is: 3 g/m Note: All necessary actions must be taken to prevent any local oil film weight exceeding 3 g/m in the area of adhesive/sealer application. Critical areas are
36、the lowest positions of parts during transport/storage, e.g. door hem flanges or other oil trapping areas. Unacceptable oil collection will require appropriate storage geometries (critical areas turned to top) or in-process cleaning operations prior to sealer/adhesive application. 3.21 LINE TRIAL Th
37、e Engineering Performance Requirements defined in this specification are based upon laboratory coupon testing and define the minimum acceptance criteria for adhesive performance. Prior to use, the adhesive must be evaluated under the production parameters of the relevant production line. The choice
38、of substrates, stamping lubricants, stamping plant-processing conditions, assembly plant processing conditions and specific design application may affect adhesive performance. Compliance with this specification does not guarantee the adhesive will function for all potential applications on a vehicle
39、. Therefore materials being evaluated for approval to this specification shall be subjected to a production trial. Functional trial results must be approved by the affected assembly operation. Results shall be made available to Materials Engineering prior to material approval and release. ENGINEERIN
