Polyether defoamers Powder
Concrete Defoamer
![]() (WPolyether powder defoamers | Xinyi synthetic powder defoamer FS202 is made of polysiloxane, special emulsifier and highly active polyether defoamer polymerized by special technology. Characterized by strong defoaming ability, low dosage, long-lasting foam suppression, good thermal stability, good fluidity, no side effects, easy transportation, etc.. In the high temperature, high alkalinity solution has a strong defoaming, foam inhibition performance. Among them, the powder polyether defoamer with special modified polyether as the main ingredient is a widely used powder defoamer. |
(1) It has fast defoaming and long-lasting defoaming effect in mortar system.
(2) By adjusting the dosage, it can optimize the size and distribution of air bubbles in the mortar system, thus improving the fluidity of mortar.
(3)It has good compatibility with different cement-based and gypsum-based cementitious materials and other additives such as retarders, expanders and hardening agents.
(4)Strong defoaming ability, low dosage, long-lasting foam inhibition, good thermal stability, good fluidity, no side effects, easy transportation.

The dosage of FS 202 is relatively low, pay special attention to the uniformity of defoamer mixing in mortar.
In the process of use, try to avoid direct contact with eyes, skin, etc., recommended the use of protective gloves and goggles, if accidentally stained, please rinse with water.
This product should be stored in the process of moisture-proof treatment..
- Packed in paper-plastic composite bag, 25kg/bag, the storage period is 12 months from the date of production, if it exceeds the shelf life, it must be verified by test and inspection before use;
- Place in a ventilated and dry place for storage, pay attention to moisture-proof treatment, avoid direct sunlight, use it in time after opening, and seal it in time if it is not used up to prevent moisture absorption and deterioration.

1,About the usage instructions of FS202.
The dosage of FS202 antifoam agent needs to be determined according to the specific situation, if the dosage is too much, it may lead to too strong antifoaming effect, which will affect the quality and performance of the product.
Although polyether defoamer is a safer defoamer, special attention needs to be paid to its safety when it is used. If it accidentally comes into contact with skin or eyes, it needs to be flushed with water immediately.
2,Scope of use:
It is mainly used for defoaming all kinds of mortar (such as building mortar, dry mortar, dry mix mortar, gypsum mortar, oil field cementing mortar, etc.), coating, paper making, water reducing agent, putty powder, desulfurization, etc.
3,procurement instructions.
