Antifoam SB is an aqueous silicone emulsion and is designed to be effective in any aqueous system,
particularly metalworking fluid emulsions and solutions. It is a white fluid which rapidly disperses
into a diluted fluid and is easily applied in low doses.
Applications
Antifoam SB is recommended for use as a foam control agent in conventional soluble oil emulsions,
semi-synthetic emulsions and in fully synthetic machining and grinding fluid solutions and
emulsions. It should be used at concentrations of 5 to 50 ppm to improve the foaming characteristics
of metalworking emulsions.
Over application of Antifoam SB may make foaming (or air entrainment) worse. In situations where
foam is a problem, we recommend that Technical Services is consulted for advice.
