Defoamer is mainly divided into mineral oil, silicone, polyether class. Defoamer works by inhibiting bubbles and removing bubbles. A good defoamer has performance of long inhibition, good effect, fast defoaming speed, no influence on the basic properties of foaming system and thermal stability.

GUUDPOLY Series Defoameris mainly used in a variety of cement-based and gypsum base mortar, concrete, asbestos, calcium silicate board, enhancer and so on.

GUUDPOLY PD305 is a kind of defoamer in powder form based on polyether with inorganic carrier. It supplies excellent anti-foam and foam control performance. It’s special designed for cement & Gypsum mortars and concretes.
