Castrol Antifoam S 105

Castrol Antifoam S 105 Antifoam Additive for Water Based Metalworking Fluids
Antifoam S 105 is a siloxane-based antifoam additive specially developed for water-based metalworking fluids. It is optimized for stability and compatibility as an effective tank-side additive for both single-sump machines as well as central systems.
It is especially useful where fast and immediate foam control is required.
Castrol Antifoam S 105 can be used in all water-based metalworking fluids where conditions of severe agitation have created unacceptable foam levels. It provides a rapid de-foaming action with a high degree of stability. Repeated use may be required for long-term effects.
