TDS-NJ-503 Defoamer

NJ-503 defoamer is a mixture of polyether surfactants and dry powder carrier, and has the following characteristics:

It can suppress bubble generation, quickly remove bubbles introduced into the mortar due to mechanical stirring or chemical reaction , and suppress bubble generation for a long time .

Defoaming typically occurs within 40–90 seconds after the mortar is mixed .

This product can be mixed with cement mortar and stored for extended periods.

This product can effectively reduces surface defects in the product, such asblack oil, black spots, and water marks.

This product is particularly suitable for systems where appearance is important, such as cement self-leveling and gypsum self-leveling systems.
