5、sed to bond sheet metal body parts. 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. 3.23). Note: Care must be taken to ensure that the local oil film weight in the area of the adhes

30、il, 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 applicable approved source list (contact materials engineering for details). The supplier must confirm the compatibility of the adhesive/sealer material to

31、 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 manufacturing engineering. The lab test panels (see para 3.23.1) must be oiled with maximum permissible oil film thickness. Reference oil for a

32、dhesive performance comparison is Fuchs Anticorit 4107S. Attention: New compatibility tests are necessary 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 mus

33、t be taken to prevent 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 geome

34、tries (critical areas turned to top) or in-process cleaning operations prior to sealer/adhesive application. 3.23.1 Oiling-Method of Lab Test Panels: 3.23.1.1 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

35、-hexane until no process traces remain on the surface. Allow to dry at ambient-temperature until the n-hexane has completely evaporated.

36、st-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 covering the glass beaker with aluminum foil as airtight as pos

37、sible. 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 heat cabin (for better oil-distribution). Apply some drops o

38、f oil on the panel and distribute them even over the panel with a lint-free cloth. Check the oil-weight. 3.23.1.3 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. After oiling weigh again. The oil coating in g/m is deri

39、ved 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 rejust the above mixture. 3.24 LINE TRIAL Materials being evaluated for approval to this specification sha

40、ll 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. 5. GENERAL INFORMATION The information given below is provided for clarification and a

41、ssistance in meeting the requirements of this specification. A1/A2/A3/A5 A4/A6 5.1 STORAGE STABILITY 12 months 6 months The material must be stable during storage in unopened drums out of direct sunlight at temperatures between 5 C and 32 C. 5.2 OPEN ASSEMBLY TIME As specified by the supplier (At th

42、e required operation temperature) Open assembly time is the maximum time interval from initial application of the adhesive to the completion of the part assembly for bonding. 5.3 MATERIAL REFERENCE All related materials used for approval of adhesives according to this specification, e.g. paint materials or metallic substrates, shall be noted in the Initial Sample Report of the adhesive.
