Castrol® Tribol 215-2 Cleanroom Grade Grease
Castrol Tribol 215-2, formerly known as Castrol Optitool 215-2, is a smooth, off-white fully synthetic NLGI 2 grade grease based upon specially selected raw materials and a proprietary thickener. This product was specifically designed for use in micro-electronic and clean room applications, which are sensitive to metallic elements and other contaminants. Castrol Optitool™ 215-2 uses no ingredients containing lithium, molybdenum, calcium, aluminum, barium, zinc or sodium as standard elements. These elements are typically found in other greases and may be contained in relatively high concentration.
