Name: Evonik TEGO Airex 800 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik TEGO Airex 800 Defoamer

Highly effective silicone-free defoamer for rapid foam break and lasting foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene dispersions.
Low dosage requirement—typically effective at 0.05–0.3 wt% in final formulation.
Non-silicone chemistry avoids surface defects such as craters, pinholes, or gloss mottle in coatings and adhesives.
Stable under shear and across a broad pH range (pH 4–12), supporting robust performance in diverse manufacturing processes.
