Castrol Surfactant S 625 is a non-ionic polyether polyol surfactant especially developed for 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. It helps improve machinibility by adjusting surface tension of working emulsions.
Castrol’s range of Surfactant additive fluids has been especially developed to improve the wetting properties of soluble metalworking fluid emulsions to improve their machining performance in critical applications like mapal reaming, tapping, etc.
