2、LUORINATED LUBRICANT, BRUSH APPLICATOR WSS-M1C282-A2 1. SCOPE WSS-M1C282-A1 The material defined by this specification is a perfluoropolyether (PFPE) oil with a gaseous fluorinated propellant used to apply the lubricant as an aerosol spray. WSS-M1C282-A2 The material defined by this specification is
3、 a perfluoropolyether (PFPE) oil, with a brush applicator to apply the lubricant. 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 oily to the touch. The lubricant is suitabl
4、e for operating temperatures between - 36 and + 204 C. 3. REQUIREMENTS 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other doc
5、uments. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 CANNISTER WEIGHT at 20 C 3.2.1 Aerosol 125g Minimum 3.2.2 Brush Applicator 14 g Minimum 3.3 BASE OIL COLOR Clear/Transparent(Visual) 3.4 BASE OIL Density at 20 C 1.91 g/ml 3

PFPE / PTFE lubricants are generally inert to painted surfaces. Grease must be tested for chemical attack to painted su
10、rfaces 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 to plastics. Grease must be tested for resistance to
11、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 application of this grease. PFPE / PTFE lubricants are g
12、enerally 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. 4.7 APPROVAL OF MATERIALS Suppliers desiring approval of
13、 their materials shall first obtain an expression of interest from Purchasing, Design or Product Development, and Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstratin
