Features Of Dow DOWSIL FS 80 Defoamer

Highly effective silicone-based defoamer for rapid foam knockdown and sustained foam control.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate, and styrene-butadiene emulsions.
Low dosage requirement—effective at 0.05–0.3 wt% in most formulations—minimizing impact on final product properties.
Thermally stable up to 120 °C, supporting high-temperature processing conditions.
Non-yellowing and non-silicone-residue-forming, preserving clarity and surface aesthetics in coatings and adhesives.

Typical Applications Of Dow DOWSIL FS 80 Defoamer

Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers).
Adhesives and sealants, particularly pressure-sensitive and water-based laminating adhesives.
Textile and leather finishing formulations requiring low-foam application.
Construction chemicals, including cementitious tile adhesives and grouts.
Water-based inks and overprint varnishes for flexible packaging and label printing.
