Silicone Defoamer water dispersing

Substances that can reduce the surface tension of water, solutions, suspensions, etc., prevent the formation of foam, or reduce or eliminate the original foam.
Defoamers should have the following properties: ① Strong defoaming power and small dosage; ② Adding to the foaming system does not affect the basic properties of the system, that is, it does not react with the defoamed system; ③ Low surface tension; ④ Good balance with the surface; ⑤ Good heat resistance; ⑥ Good diffusivity and permeability, and a high positive spreading coefficient; ⑦ Chemical stability and strong oxidation resistance; ⑧ Good gas solubility and permeability; ⑨ Low solubility in foaming solutions; ⑩ No physiological activity and high safety.
Defoamers are widely used, such as food industry, papermaking industry, water treatment, oil production industry, printing and dyeing industry, coating industry, detergent industry, rubber latex industry, aerosol industry, daily chemical industry, pharmaceutical industry, dairy products industry, etc.
