J.SchultWP 3948-a Page 1 of 5 SEALER, SOLVENT RELEASE, NON-SETTING WSK-M4G342-A1/A21. SCOPEThe material defined by this specification is a non-setting sealingco

2、mpound which is resistant to temperatures between - 40 C and + 250 Cwithin joint faces. The sealer will resist automotive fluids well in excessof normal operating temperatures and gives good clamping force retentioneven where vibration may be encountered.The sealer is supplied, in a range of dilutio

3、ns, with a solvent which isallowed to evaporate between application and fitting to leave a flexible,coherent film.2. APPLICATIONThis material was originally released for sealing clean mating surfaces onengine or transmission and/or as specified on Engineering drawings.3. REQUIREMENTSThe grade of sea

4、ler supplied shall be suitable for the method ofapplication as defined by the relevant Component Engineer and ManufacturingDivision.3.1 STATISTICAL PROCESSSuppliers must conform to the requirements of Ford Quality SystemStandard Q-101. A mutually acceptable Control Plan as describedtherein is requir

5、ed 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/orthermal analysi

6、s 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 correspond to the referen

7、ce standard when testedunder the same conditions.3.3 CONDITIONING AND TEST CONDITIONSAll test values indicated herein are based on material conditioned ina controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relativehumidity for not less than 24 h prior to testing and tested under thesame conditions
