Name: Kemira DF-A-622 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Kemira DF-A-622 Defoamer

Highly effective silicone-based defoamer for rapid foam knock-down in demanding aqueous systems.
Excellent long-term foam suppression and refoaming resistance under dynamic process conditions.
Good compatibility with anionic, nonionic, and cationic surfactants commonly used in industrial formulations.
Low dosage efficiency—effective at 0.01–0.1% w/w depending on system severity.
Stable across a broad pH range (pH 4–12) and tolerant to elevated temperatures up to 90°C.

Typical Applications Of Kemira DF-A-622 Defoamer

Paints and coatings manufacturing, including architectural and industrial waterborne systems.
