General Qualities & Characteristics

RODS C41 is an extreme pressure, biostable semi synthetic coolant containing ingredients carefully selected for their low order of toxicity and which are designed to form a high performance coolant when diluted with water.

Typical Applications

Sawing, turning, milling, drilling, grinding.

Material Compatibility

Suitable for machining a wide variety of materials including cast iron, mild steels, cuprous alloys and stainless steels.

Water Compatibility

Tolerant of a wide range of water hardnesses. Low foaming in softer waters and low scumming in hard water.

Sump Life

A very long sump life is ensured by making use of biostatic raw materials where possible and combining the remainder with appropriate bactericides and fungicides. It offers therefore great resistance to bacterial breakdown.


Milling and threading 5 - 7%

Sawing and general machining 4 - 5%

Grinding 3%

Product Mixing

The use of automated mixing systems is recommended. If the fluid is to be mixed manually, always add the concentrate to the water with maximum agitation.

The emulsion strength should always be checked using a calibrated refractometer.
