Defoamers Series

PH-Resistant Antifoaming Agent

PH-resistant antifoaming agent, DDAA-302, is made by silicon-type super-surfactant and exclusive formula technology, which represents the leading technology around the world. Technique starting point of antifoaming agent is high; meanwhile, it pertains to the latest generation. The antifoaming agent has overcome the shortages of short time of defoaming and foam inhibiting of traditional organo-silica, and its weak adapting capability under server chemical and physical conditions for long time. It shows very good defoaming and foam inhibiting effect under severe acid, alkaline and other complicated circumstances. The product is widely used in the production process to defoam and inhibit foam under pH and severe acid and alkaline conditions, such as humic acid (sodium salt and sylvite), hydrometallurgy, dyeing and printing, paper making, cleaning fluid, paint, water treatment and etc.

Product Characteristics:
1. Good defoaming effect, long foam inhibiting time, may meet the requirements of controlling foam under acid and alkaline and other complicated conditions;
2. Less usage, usually 0.01 ~ 0.5% dosage will achieve ideal effect.
