2、1 of 2 GREASE, SILICONE, NLGI GRADE 2 WSS-M1C171-A3 1. SCOPE The material defined by this specification is a silicone compound. 2. APPLICATION This specification was released originally as a corrosion and water washout resistant grease used for steering and suspension ball joint boot seals where rub

3、ber to metal lubrication is required. This material is compatible with thermoplastic and thermosetting elastomers typically used for ball joint boot seals. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard R
