I. Product Introduction     
Water treatment defoamer is an emulsion-type product primarily composed of polysiloxane, emulsifiers, dispersants, and other components, meticulously crafted through a special process. It is specifically designed for defoaming in various industrial and domestic wastewater applications. This product exhibits excellent acid and alkali resistance, superior stability, easy dispersion in water, and a wide applicable temperature range. It rapidly eliminates stubborn foam in foaming systems and provides long-lasting foam suppression.

II. Product Characteristics 
1. Acid and alkali resistance, high shear resistance, and a broad applicable temperature range.
2. Low dosage, low consumption, low COD, and low cost.
3. Excellent product stability, easy dispersion in water, with no impact on water quality testing and discharge indicators.
4. Strong versatility, capable of quickly eliminating foam and providing long-term foam inhibition.
5. Comparable to imported brands in performance, with a more competitive price.
