SCOPE The material defined by this specification is an ADFOSY sprayable, one component, solvent free, heat curing adhesive ba

3、sed on epoxy resin. 2. APPLICATION This specification was released originally for material used to reinforce and stiffen sheet metal body panels. The materials are applicable on oiled surfaces with acceptable oil film weights (European applications limit the oil/pre-lubricant film weight to max 3 g/

4、m, see para. 3.10). 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 surface prior to sealer/adhesive application

5、is necessary to avoid critical film thickness values, which would then cause malfunction of the sealer/adhesive 3.

23、ITY & REFERENCE OIL (FOR EUROPE) All materials released to this specification must be applicable to oiled surfaces, including corrosion protection oil, wash oils, pre-lubricants, draw oils, hotmelts etc. The approved products for use in Ford of Europe or the European brands are listed in the applica

24、ble approved 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

25、Ford manufacturing engineering. The lab test panels (see para 3.10.1) must be oiled with maximum permissible oil film thickness. Reference oil for adhesive performance comparison is Fuchs Anticorit 4107S Attention: New compatibility tests are necessary if the oil grade of the affected part is change

26、d! Nominal oil film weight is 1 - 1.5 g/m ENGINEERING MATERIAL SPECIFICATIONWSK-M2G384-A1 Printed copies are uncontrolled Copyright 2007, Ford Global Technologies, LLC Page 5 of 6 The maximum permissible oil weight for full adhesive performance is 3 g/m Note: All necessary actions must be taken to p

27、revent any local oil film weight exceeding 3 g/m in the area of adhesive/sealer application. Critical areas are 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

28、 areas turned to top) or in-process cleaning operations prior to sealer/adhesive application. 3.10.1 Oiling-Method of Lab Test Panels 3.10.1.1 Test-Panel Cleaning Clean the test-panel with the lint-free cloth soaked with the solvent n-hexane. Rinse both sides of the test panel with n-hexane until no

29、 process traces remain on the surface. Allow to dry at ambient-temperature until the n-hexane has completely evaporated. 3.10.1.2 Oiling the Test-Panel Small panels (Tensil-, Shear-, Peel-Adhesion): Immediately after air drying, immerse the panel in a 250 ml glass beaker, filled up to 200 ml with a

30、mixture of 10% n-hexane/90% reference oil. Prevent evaporation losses by covering the glass beaker with aluminum foil as airtight as possible. After immersion for 1 minute, remove the panel from the glass beaker. Allow the panel to drain in a vertical position at ambient temperature. Other panels (f

31、.ex. Hardness): The cleaned panel should be warmed up for a short time in a heat cabin (for better oil-distribution). Apply some drops of oil on the panel and distribute them even over the panel with a lint-free cloth. Check the oil-weight. 3.10.1.3 Checking of Oil Coating/Weight A test panel prepar

32、ed as per 3.10.1.1 is weighed on an analytic scale with a precision of 0,001 g. After oiling weigh again. The oil coating in g/m is derived from the weight difference in relation with the panel-dimensions. If the oil-weight deviates approx. +/- 0.3 g/m from the specified oil-weight, the panel can be

33、 used. Otherwise oil again or re-adjust the above mixture. 3.11 LINE TRIAL 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 and Design Engineering. Results shall be made

34、 available to Materials Engineering prior to material approval and release.
