CHEMPOL 5103 Water Soluble Cutting Fluid Additive

Multi-Purpose Emulsifier Base for Soluble Oils-Nitrite Free


CHEMPOL 5103 has been formulated to meet the requirements for the preparation of soluble oils from paraffinic and naphthenic base oils, which will give stable milky emulsions in all types of water. It is also suitable as the base for the preparation of translucent semi-synthetic micro-emulsions and heavy-duty EP emulsions.


It is a blend of emulsifying agents, wetting agents, and rust inhibitors, together with solvent-refined mineral oils. It also contains biocides and fungicide additives to give the finished soluble oils a long service life and prevent emulsion breakdown and spoilage.

It is an extremely versatile product for medium-cutting operations and provides all the lubrication and cooling properties necessary to ensure a good workpiece finish and extended tool life. It is suitable for ferrous and non-ferrous metals in turning, milling, drilling, tapping, threading and cold sawing operations.

For improved emulsion stability the concentrate can be adjusted for the base oil used by the addition of more acid (Olein, Tall oil Distillate) or by more alkali (Triethanolamine, Potassium Hydroxide).

Soluble oil formulations based on CHEMPOL 5103:

Typical opaque soluble oil formulations

A treat rate of 15-20 % wt in paraffinic base oils yields a concentrate, which forms stable emulsions (5%) in medium hard water. The pH-value of a 5% emulsion is between 8.5-8.8. The addition of biocide is recommended.

Suggested minimum treatment levels of CHEMPOL 5103 in base oil:

150 SUS Paraffinic Oil:                        from 15 % w/w
100 SUS Paraffinic Oil:                        from 17 % w/w

Note: for improved emulsion stability in these formulations the concentrate can be adjusted for the individual base oil used by the addition of more acid (eg. Distilled Tall Oil) or by more alkali (eg. Potassium Hydroxide). Supplementary biocides are customarily added to the finished product.

Handling/ Precaution

When handling this product a MAXIMUM temperature of 60°C should be observed for storage, unloading and blending. However, it is strongly recommended that for long-term storage the temperature should not exceed 50°C. For detailed data, please refer to the relevant MSDS.
