Name: Dow 71 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow 71 Defoamer

Highly effective silicone-based defoamer for rapid foam knock-down and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.
Low dosage efficiency — typically effective at 0.05–0.3 wt% active in final formulations.
Thermally stable up to 120°C, supporting high-temperature processing conditions.
Non-yellowing and non-staining, preserving clarity and color integrity in sensitive coatings and adhesives.

Typical Applications Of Dow 71 Defoamer

Architectural and industrial waterborne paints and coatings.
Adhesives and sealants, especially pressure-sensitive and latex-based formulations.
Textile and leather finishing auxiliaries.
Construction chemicals, including cementitious grouts and tile adhesives.
Water treatment systems requiring controlled foaming during dosing or mixing.
