2、EThe material defined by this specification is a isocyanate hardener whichcures in connection with polyol based adhesive, mineral filled, solventfree to ESK-M2G365-A1 at room temperature within approx. 24 h to reachabout 80 % of final adhesion strength.2. APPLICATIONThis specification was released o
3、riginally for a material mixed withESK-M2G365-A1 to bond car cross beam (e-coated) to brackets (chromatedsteel, dirt and grease free).3. REQUIREMENTS3.1 STATISTICAL PROCESSSuppliers must conform to the requirements of Ford Quality SystemStandard Q-101. A mutually acceptable Control Plan as described
4、therein is required for material/source approval. Appropriatestatistical tools must be used to analyze process/product data sothat variation in the final product is continuously reduced.3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSISFord Motor Company, at its option, may conduct infrared and/
5、orthermal analysis of material/parts supplied to this specification.The IR spectra and thermograms established for initial approval shallconstitute the reference standard and shall be kept on file at thedesignated material laboratory. All samples shall produce IR spectraand thermograms that correspo
