Product Description

Unicool 427 is a heavy-duty semi-synthetic metalworking fluid designed for machining and grinding of steel, cast aluminum, and aluminum-magnesium alloys. Unicool 427 contains a combination lubricity and EP package for use in a variety of machining operations. Unicool 427 can effectively be employed in high pressure, high volume CNC machining due to its excellent anti-foaming characteristics.

Features and Benefits

  • Excellent low foam characteristics
  • Good parts and machine rust protection
  • Does not stain aluminum
  • Contains unique lubricity agents designed for high performance on steel and aluminum
  • Rejects hydraulic and other tramp oils
  • Does not contain chlorine, triazine, or secondary amines

Recommended Use and Concentrations

Unicool 427 should be diluted with demineralized (RO or DI) water. If desired, your DCT representative can arrange laboratory water testing. Makeup for evaporation may be best accomplished with DI or RO water to prevent hard water buildups. Unicool 427 is recommended for use at 5 – 15% in the machining of cast iron, aluminum, steel and stainless in multiple operations including grinding, drilling, milling, turning, tapping and broaching. Higher concentrations may also be used for one-of-a-kind jobs within the plant. Product concentration is easily controlled by refractometer. Product pH and bio-control are typically maintained by product makeup without the addition of additives.
