Excellent emulsification for both paraffinic and naphthenic base oils with appropriate formulation. Capable of producing stable micro-emulsions at low concentrations. |
| 500 H |

Typical Applications
These sodium sulphonate grades represnt the high quality available on the market today. Produced from 100% natural mineral oil aromatics from paraffinic base oils. The products find application typically as emulsifiers for emulsion and micro-emulsion based metalworking fluids. The higher molecular weight grades offer a significant corrosion inhibiting credit and are particulary useful in amine free fluids.
