Application method:

Defoamer can be added after foam generated as foam suppression components according to the different system, usually adding defoaming agent for 10 to 1000 PPM, the best adding quantity test according to particular case decided by the customer.


Defoamer can be used directly, can also be used after dilution.
in the foaming system can fully mixing dispersion, can be added directly, without dilution.
For dilution, cant add water into it directly, it is easy to appear layer and demulsification, then affect the product quality.

diluted with water directly or other incorrect consequences method , we company shall not bear the responsibility.


application field:
papermaking chemical pulping high temperature vacuum or pressure in the defoaming in pulp washing machine;
When the alkali refining agent of textile industry, inhibit elimination of treatment before;

circuit board cleaning;

oil mud defoaming in the process of mining;

textile printing and dyeing processing

agricultural chemicals;



1.Avoid contacting with eyes, skin and clothing. Otherwise, wash with a flush of water

2.Refer to Material Safety Data Sheet (MSDS) for complete handling and hazard data.


Low from polysiloxane, modified polysiloxane, silicone resin, white carbon black, dispersing agent and stabilizer, etc;
Low at low concentrations can maintain good elimination bubble suppression effect;
Low foam suppression performance is prominent;
Low easily dispersed in water;
The compatibility of low and foaming medium;
Low to prevent the growth of microorganisms.


package and storage:

Package:25kg/drum,200kg/drum 1000kgs/IBC


1,According to the different foaming system, regulate the usage, it is recommended to use range between a few parts per thousand to several per.

2,When using water or working liquid dilute stir to join or directly to join.

3,Can be used in the water phase system under 100 ℃.

4,When using, shall not be brought into other items, the other pay attention to the preservation, if there are any strange, stir when using, do not affect performance. Packaging, storage, transportation containers must be tightly closed, around 25 ℃ environment.


Shelf life :6 month.
