Mixing & use
Maintain a working fluid refractometer reading of 7-18. Readings below 7 can promote bacterial growth and fluid deterioration; readings above 18 may increase skin irritation.
| Machining load | Working fluid refractometer reading | Mixing ratio (concentrate : water) | Daily top-up fluid |
|---|---|---|---|
| Medium duty | 8-12 | 1:10 - 1:6 | Daily top-up: refractometer reading 5-7 |
| Heavy duty | 12-18 | 1:6 - 1:4 | Daily top-up: refractometer reading 7-10 |
Formulation
Base oil, rust inhibitor, emulsifier, lubricant, extreme-pressure additive, high-performance corrosion inhibitor, auxiliary additives, biocide and deionized water. The formulation contains no nitrite ions, hexavalent chromium ions, sodium nitrite or phenol.
Use & handling
Gradual color darkening during storage is normal and does not affect use. The high-molecular-weight siloxane foam-control component may settle during prolonged storage; this does not affect use. Do not mix with other oils.
