Wacker 850E defoamer is a high concentration, medium to low viscosity silicone defoamer emulsion with strong defoaming and antifoaming properties. It is used for defoaming in pulp and paper mills. The 850E exhibits significant instantaneous bubble bursting and excellent continuous defoaming capabilities. Adding it at a concentration of 0.01 - 1.00% before grinding or mixing yields good antifoaming effects. It can also be added afterward, but ensure thorough mixing.
