B 50 is a silicone antifoam formulated for wide range of chemical processes. It is particularly indicated for formulation that needs low concentration of antifoam with high concentration of silicone and high efficacy. Added in detergents it allows to control the foam and to avoid opal effects on detergent systems, also for systems at low viscosity. B 50 is used also in waste water treatment systems and biological purifier. B 50 is stable during the storing for long time and maintains intact its characteristics of antifoam and deaerating, at high temperature also with low dosage.
