SCOPE The materials defined by these specifications are spot weldable, heat curing, heat expanding sealers based on

4、polyisobutylene or polyacrylic ester. 2. APPLICATION WSK-M4G325-A1: This specification was released originally for dimensioned materials used for sealing spot weld joints on the body-in-white. It is applied to oiled surfaces in the form of self adhesive strips. WSK-M4G325-A2/A3: These specifications

5、 were released originally for non-dimensioned materials used for sealing spot weld joints on the body-in-white. It is applied to oiled surfaces by an extrusion apparatus. WSK-M4G325-A4/A5: These specifications were released originally for non-dimensioned materials used for sealing joints in BIW. It

6、is applied to oiled surfaces by an extrusion apparatus. 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/m, see para. 3.7). Note: Care must be taken to ensure that the local oil film weight in th

7、e 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 is necessary to avoid critical film thickness values, which would then cause malfunction of

8、 the sealer/adhesive. 3. REQUIREMENTS: Material specification requirements are to be used for initial qualification of materials. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-

38、 Global Technologies, LLC Page 7 of 8 3.7 OIL COMPATIBILITY & 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

39、 Europe or the European brands are listed in the applicable 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 v

40、ehicle production - in a line trial in cooperation with Ford manufacturing engineering. The lab test panels (see para 3.7.1) must be oiled with maximum permissible oil film thickness. Reference oil for adhesive performance comparison is Fuchs Anticorit 4107S. Attention: New compatibility tests are n

41、ecessary if the oil grade of the 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 ap

42、plication. 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 areas turned to top) or in-process cleaning operations prior to sealer/adhesive a

43、pplication. 3.7.1 Oiling-Method of Lab Test Panels: 3.7.1.1 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 process traces remain on the surface. Allow to dry at ambient-temperature until th

44、e n-hexane has completely evaporated. 3.7.1.2 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 mixture of approx. 10% n-hexane/90% reference oil. Prevent evaporation losses by cover

45、ing 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.ex. Hardness): The cleaned panel should be warmed up for a short time in a he

46、at 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. 3.7.1.3 Checking of Oil Coating/Weight A test panel prepared as per 3.23.1.1 is weighed on an analytic scale with a precision of 0.001 g.

47、 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 used. Otherwise oil again or re-adjust the above mixture. ENGINEERING MATERIAL
