Castrol® Optitool™ 215-2 Cleanroom Grade Grease

Product Information



Description
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, phosphorous or sodium as standard elements. These elements are typically found in other greases and may be contained in relatively high concentration. Castrol Optitool™ 215-2 provides outstanding low friction and anti-wear properties making it ideal for use in all precision requirements and applications which require exceptional lubricity.

Temperature Range
-40°C to 150°C maximum (-40°F to 302°F maximum)

Uses
Castrol Optitoo™ 215-2 is intended for use on ball, roller, and needle bearings, linear motion components, carriages, lead screws, gears, sliding and roller surfaces, instruments and precision equipment.

Limitations
Castrol Optitool™ 215-2 is compatible with many lubricants but certain adverse reactions can occur when mixing greases. Mixing of incompatible greases can cause failure and/or decreased performance in certain applications. Before use in any system, consider doing some testing to make sure this product is appropriate for your particular application. It is also important to check for compatibility with the grease you are presently using, and we at SPI Supplies would always try our best to help you with this information.
