Opticool 372(E) (EMEA Only) - Chesterton

Enhanced TDS

Identification & Functionality

Base Oil Type: Naphthenic
Product Type: Metalworking Fluids
Technologies: Ready-to-Use Products
Product Families: Ready-to-Use Products — Fluids & Lubricants
Metalworking Fluids
Composition: OPTICOOL 372(E) is compounded with the most effective extreme pressure and anti-weld additives. These additives along the base lubricant provide both hydrodynamic (barrier film) and boundary lubrication, which effectively extend tool life and improve surface finish. A biological preservation package provides microbial control virtually eliminating any adverse effects on the skin. OPTICOOL 372(E) does not contain nitrites, phenols, sulfur, mercurials, formaldehyde or chlorinated additives.

Directions: OPTICOOL 372(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 372(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 218 HDP Cleaner at 5% concentration. Circulate the cleaner for up to 2 hours through all lines, tool holders and work pieces. Dilutions in excess of 40:1 are not recommended since the corrosion protection and resistance to bacterial attack will be reduced.
Recommended Starting Dilutions: Alloy Steels Steel Aluminum

Technical Details & Test Data

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 chart above 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 Opticool additives 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: If permitted by local or state regulation, the product may be discharged into a waste disposal system, but only after the water insoluble fraction is removed with acid-alum or alum-polymeric demulsifiers.
