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 PD303 is a kind of defoamer in powder form based on polyether with inorganic carrier. It supplies ideal anti-foam and foam control performance.

Physical Specification

Properties / Benefits

GUUDPOLY PD303 provides the following benefits:

●       Outstanding anti-foam and foam control performance

●       Excellent long-term stability in dry mortars

●       Improves surface properties of leveling compounds

●       No negative impact on setting time

●       Very low contribution to VOC

Application

GUUDPOLY PD303 may be used in various applications as follows:

●       Ceramic tile adhesive

●       Tile grouts & Grouts mortar & Joint filler

●       Cement and anhydrite based Screeds

●       Industrial Clearance (bottle or solid matter)

●       Adhesives (Starch adhesive)

●       Petroleum processing (drilling, cementing)

Dosage and Handling

Building Mortars: GUUDPOLY PD303 is added to other powdery components and mix to get a homogenous formulation. The dosage may vary from 0.05%-0.3% of the total dry material by weight.

Clearance: add directly or add to mundificant, suggest dosage may vary from 0.1%~0.5% of total formulation by weight.

The actual required dosage should be evaluated in suitable tests prior to final application.
