COOLEDGE BI

DESCRIPTION :

Castrol  Cooledge B I  is a general purpose soluble oil with good lubricity characteristics.  When  mixed with water, it forms a good quality milky emulsion.

APPLICATIONS:

Castrol Cooledge BI is suitable for multi metal operations in turning, drilling and milling operation.   It is usually used in small machine shops requiring a stable product which offers versatility at a reasonable cost.  It is not the first choice for large central or high pressure coolant system.

RECOMMENDED DILUTIONS  :

NB      :  To maintain the outstanding biological resistance, it is recommended that the emulsion  strength should not be allowed to fall below 4%

BENEFITS:

* Stable in use even in hard water environment.

* Good anti-scumming properties

* Good multi metal suitability, including aluminiumalloys.

* Ideal for small to medium size work shops.

* Effective biocide system to combat bacterial degradation, thus extending coolant life.
