- Composition
- OPTICOOL 972(E) offers maximum lubrication and the most effective extreme pressure and anti-weld additives. These additives along with the base lubricant provide both hydrodynamic (barrier film) and boundary lubrication which effectively extend tool life and result in superior surface finish. The bio-resistant additive package reduces the odors associated with emulsion coolants.
- OPTICOOL 972(E) does not contain mineral oil, chlorine, sulfur, nitrites or mercurials.
- OPTICOOL 972(E) contains EP and lubricity additives for those extreme jobs that require the additional pressure resistance.

- Directions
OPTICOOL 972(E) should be added to water at the recommended starting point. It is important that the coolant be added to water. Do not add water to the coolant. Before adding OPTICOOL 972(E) to any reservoir remove old coolant, fines and residues from the system. Drain the old coolant from the sump; charge the system with Chesterton’s 218(E) HDP at 5% concentration. Circulate the cleaner for up to 2 hours through all lines, tool holders and work pieces. Dilutions in excess of 25:1 are not recommended since the corrosion protection provided by OPTICOOL 972(E) and its internal resistance to bacterial attack will be reduced.

Storage & Handling
- Coolant Maintenance
Concentration of the fluid changes constantly during use due to evaporation and “drag out” on chips. Volume loss to evaporation is 100% water. For maximum performance, the concentration should be monitored and maintained on a regular basis. The Brix factor gives the approximate relationship between coolant concentration and refractometer reading. Often it is helpful to monitor the sump’s pH. If the pH is or drops, below 8.5 the sump is imbalanced and requires conditioning. Adding fresh coolant or a sump additive restores the pH level, maximizing coolant performance.
- Clean Up
Residual Coolant on parts, equipment and machine tools is easily removed by rinsing with water.
- Waste Disposal
Primary treatment by an oil separation or settling tank will remove solids and tramp oil. At this point, it is possible that adjustments to the concentration could be made and the coolant may be reclaimed for continued use.
