Name: Dow 74 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow 74 Defoamer

Highly effective silicone-based defoamer for rapid foam knockdown in demanding aqueous systems.
Excellent compatibility with a broad range of water-based formulations, including those containing surfactants and electrolytes.
Low dosage efficiency—provides robust defoaming performance at concentrations as low as 0.01–0.1% active.
Thermally stable up to 120 °C, maintaining performance during high-temperature processing steps.
Non-volatile and non-silicone-residue-forming, minimizing surface defects in final coatings and films.

Typical Applications Of Dow 74 Defoamer

Water-based architectural and industrial coatings (e.g., acrylic and PVA emulsion paints).
Adhesives and sealants manufacturing, especially during high-shear mixing and dispersion.
Textile auxiliaries, including dyeing, printing, and finishing baths.
Agrochemical formulations such as suspension concentrates (SC) and emulsifiable concentrates (EC).
Cleaning and detergent systems where persistent foam interferes with rinsing or automated dispensing.
