Features Of Dow DOWSIL FS 025 Defoamer

Highly effective silicone-based defoamer for rapid foam knockdown and sustained foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.
Low dosage requirement—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-silicone-residue-forming, preserving clarity and surface aesthetics in coatings and adhesives.

Typical Applications Of Dow DOWSIL FS 025 Defoamer

Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers).
Water-based adhesives and sealants, including laminating and construction-grade formulations.
Textile printing pastes and pigment dispersions requiring low-foam rheology control.
Building materials such as cementitious tile adhesives and grouts.
Industrial cleaning solutions where foam interference must be minimized during automated dispensing or spray application.
