Castrol Surfactant S 620
01736 757002Castrol Surfactant S 620 Additive for Metalworking Fluids
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.
Castrol’s range of industrial surfactant fluids helps to adjust the surface tension of the 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.
