HY-611 Silicone Defoamer
HY-611 is a high-content silicone defoamer that provides lasting defoaming performance even in small amounts without affecting the basic properties of the foaming system. It is a water-based system, easily soluble in water, with good diffusion, penetration and heat resistance, high chemical stability and strong oxidation resistance. It can be used in acids, alkalis, electrolytes and hard water.
Fast defoaming and foam suppression; non-corrosive, non-toxic, no adverse side effects, highly environmentally safe

Usage Method
1. Determine the foam source:Determine the cause and location of foam generation so as to effectively control the addition of the defoamer.
2. Determine the dosage:Determine the dosage according to the severity of the foam and the characteristics of the system. The recommended dosage is 0.1%-0.5% of the total system, and the specific dosage should be adjusted according to the actual foaming situation.
3. Addition method:It can be added directly or after dilution; a small-scale trial is recommended first.
4. Uniform dispersion:Add with uniform dispersion during the production process to ensure full contact between the defoamer and the foam.
