Castrol Antifoam™ S 105 is a siloxane based antifoam additive especially developed for water based 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 is especially useful where fast and immediate foam control is required.

Castrol Antifoam S 105 can be used in all water based metal working fluids where conditions of severe agitation have
created unacceptable foam levels. It provides a rapid defoaming action with a high degree of stability. Repeated use
may be required for long term effect.

Castrol Antifoam S 105 should only be used after consultation with Castrol’s Service Representative. Recommended
dosage for a foaming system is between 50 – 500 ppm by volume of emulsion.

Please shake before use to homogenized the fluid.
