Castrol Surfactant™ S 620 is a superior quality emulsifying additive based on highly effective non-ionic surfactant especially developed for mineral oil based soluble metalworking fluids. It is optimised for stability and compatibility as an effective tank-side additive for both single sump machines as well as central systems.
Application:
Castrol Surfactant S 620 helps to adjust surface tension of working emulsion thereby improving detergency and chip build up. Its superior wetting properties help keep the residues formed during machining soft and easy to clean. It shows good solubility in water and is low foaming over a wide temperature range.
