Ecocool D

Semi-synthetic coolant for aluminium machining

Ecocool D has been developed to machine aluminium and its alloys where maximum lubricity and extreme pressure characteristics are essential. When mixed with water, Ecocool D produces an opaque pale pink emulsion with a mild odour. Ecocool D is ideal for use in difficult machining operations or where surface finish is critical. Ecocool D does not contain nitrite.

Benefits of using Ecocool D

Low foaming

Good corrosion protection

Will not absorb excessive amounts of tramp oil

Good lubricity

Biostable

Application:

Designed for use in both central systems and individually-filled machines.
Recommended concentrations:

Aluminium
- General machining	5-7%
- Grinding	3-4%
