Name: Dow 7305 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow 7305 Defoamer

Highly effective silicone-based defoamer for rapid foam knockdown and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate emulsions, and styrene-butadiene polymers.
Low dosage requirement—typically effective at 0.05–0.3 wt% active in final formulation.
Thermally stable up to 120 °C, maintaining performance during high-shear mixing and elevated processing temperatures.
Non-yellowing and non-staining, preserving clarity and color integrity in sensitive coatings and adhesives.

Typical Applications Of Dow 7305 Defoamer

Architectural and industrial waterborne paints and coatings.
Adhesives and sealants, especially pressure-sensitive and latex-based formulations.
Textile and leather finishing auxiliaries requiring low-foam processing.
Construction chemicals, including cementitious tile adhesives and grouts.
Water-based inks and overprint varnishes for flexible packaging.
