9、TERIAL PERFORMANCE PROPERTIES Parts prepared with materials according to these specifications shall meet all requirements of performance specification WSK-M11P47-A5. 3.7 QUALITY The material shall be a smooth homogeneous mixture, free from foreign material and properties detrimental to normal produc

10、tion use. It shall be consistent in color and texture and free from objectionable odors during normal production and storage. It shall be suitable for the intended application. 3.8 SOURCE OF SUPPLY Both components, WSS-M2G567-A and WSS-M2G567-A2, must be bought from the same supplier. 3.9 OIL COMPAT

11、IBILITY & REFERENCE OIL (EUROPEAN APPLICATIONS) 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

12、 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 vehicle production - in a line trial in co

13、operation with Ford manufacturing engineering. The lab test panels (see para 3.9.1) 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

14、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 the lowest p

15、ositions 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. 3.9.1 Oiling-Method of Lab Tes

16、t Panels 3.9.1.1 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 the n-hexane has completely evaporated. ENGIN

18、00 ml with a 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. Ot

19、her 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 of oil on the panel and distribute them even over the panel with a lint-free cloth. Check the oil-weight. 3.9.1.3 Checking of Oil Coating/Weight A test

20、panel prepared as per 3.9.1.1 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 p

21、anel can be used. Otherwise oil again or rejust the above mixture. 3.10 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. Results shall be made available to M

22、aterials Engineering prior to material approval and release. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of these specifications. 4.1 MATERIAL REFERENCE All related materials used for approval of adhesives according to t

23、his specification, e.g. paint materials or metallic substrates, shall be noted in the Initial Sample Report of the adhesive. 4.2 STORAGE STABILITY (Single Materials) (From date of receipt at Ford Motor Company) WSS-M2G567-A 6 months WSS-M2G567-A2 6 months The material must be stable during storage in unopened drums out of direct sunlight at temperatures between 5 C and 32 C.
