SCOPE The material defined by this specificati
2、on is a perfluoropolyether (PFPE) oil with a gaseous fluorinated propellant used to apply the lubricant as an aerosol spray. 2. APPLICATION This specification was released originally for anti-squeak purposes for body interior. The aerosol spray produces a PFPE oil film on the surface which can feel
3、oily to the touch. The lubricant is suitable for operating temperatures between - 36 and + 204 C. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.2
4、 CANNISTER WEIGHT at 20 oC 125g Minimum 3.3 BASE OIL COLOR Clear/Transparent(Visual) 3.4 BASE OIL Density at 20 oC 1.91 g/ml 3.5 BASE OIL Viscosity at 40 oC 150 170 mm2/s (ASTM D445) 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requir
5、ements of this specification. Grease approved to this specification should have the following typical properties. 4.1 BASE OIL Viscosity Index 124 (ASTM D2270) 4.2 BASE FLUORINATED POLYMER 3 8% (According to formulation, ASTM D128) 4.3 DROPPING POINT Not Available (ASTM D556, ASTM D 2265, DIN ISO 21
6、76) The test gives inaccurate results on solid thickened greases and would show a drop of oil from the cup at temperatures under 200 C even for greases that work at higher temperatures.

Note: Not tested for initial application of this grease. PFPE / PTFE lubricants are generally inert to painted surfaces. G
8、rease must be tested for chemical attack to painted surfaces for applications that come in contact with paint surfaces, ex. E-coat and powder coat. 4.6.2 Resistance to Stress Cracking (FLTM BO 127-03) Note: Not tested for initial application of this grease. PFPE / PTFE lubricants are generally inert
9、 to plastics. Grease must be tested for resistance to stress cracking when used for additional applications that come in contact with polymers such as PC, ABS, PC+ABS, ASA or acrylic 4.6.3 Elastomer Compatibility, NBR (ASTM D 4289, DIN 53505, DIN 53504, 70 hrs, 100 C) Note: Not tested for initial ap
10、plication of this grease. PFPE / PTFE lubricants are generally inert to rubber. Grease must be tested for elastomer compatibility when used for additional applications that come in contact with elastomers. Application specific elastomer should be used for testing instead of a reference elastomer. . 5. SUMMARY OF REVISIONS
