Defoaming Powder
Product FeaturesDefoaming powder is a solid, powdered form of defoamer designed to rapidly eliminate and effectively suppress foam in aqueous systems over the long term. It is especially suitable for dry powder products where adding water is not feasible, as well as for harsh environments involving strong acids or alkalis.

Product Advantages
- The key differences between this product and liquid defoamers lie in its "dry" and "stable" characteristics: being free of moisture, it can be easily mixed directly with dry raw materials such as cement, laundry detergent, or cleaning agents, simplifying both storage and transportation.
- Moreover, specifically engineered for demanding conditions, it maintains stable and efficient defoaming performance even under strong acidity, alkalinity, high temperatures, or high shear forces—conditions that many liquid defoamers struggle to handle.
FAQ
-
What should I do if the defoaming effect is unsatisfactory?
There are three possible reasons: first, insufficient dosage—gradually increase the amount to test; second, inadequate mixing—ensure the powder is thoroughly dispersed in the system; third, improper addition point or method—add at the source of foam generation, or switch to a water solution for better results.
-
Shrinkage or surface defects occur after addition?
This is usually caused by excessive dosage or insufficient dispersion. Reduce the dosage appropriately and extend mixing time to ensure complete dispersion. After adding defoamer, it is recommended to wait at least 24 hours before testing material performance.
-
What should I do if the powder has clumped due to moisture?
Defoaming agent powder should be stored under low-temperature, dry conditions to prevent moisture absorption. Once clumped due to moisture, it may have lost effectiveness or become difficult to disperse evenly; therefore, further use is not recommended.
