Name: Dow DOWSIL 1315 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow DOWSIL 1315 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 copolymers, and styrene-butadiene emulsions.
Low dosage efficiency—effective at typical use levels of 0.05–0.3 wt% in final formulations.
Thermally stable up to 120 °C, maintaining performance during high-shear mixing and elevated processing temperatures.
Non-yellowing and non-staining, supporting clarity and color fidelity in sensitive coatings and adhesives.

Typical Applications Of Dow DOWSIL 1315 Defoamer

Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers).
Water-based adhesives and sealants, including PVA and EVA formulations.
Textile and leather finishing auxiliaries, particularly in dyeing and padding baths.
Construction chemicals such as cementitious tile adhesives and grouts.
Industrial cleaning formulations and metalworking fluid concentrates.
