2、al defined by this specification is a synthetic lubricating grease consisting of a polyalphaolefin base oil (PAO), lithium soap thickener, solid lubricants, and a tackifier to provide good lubrication and added protection against washout by splash water. 2. APPLICATION This specification was release
3、d originally for a grease to be used on interior door hardware (e.g., window tracks, window regulators, etc.) where good lubrication and protection against washout by splash water is required. The lubricant is suitable for operating temperatures between - 40 and + 150 C. 3. REQUIREMENTS 3.1 STANDARD
