Elementis DAPRO DF 677 Defoamer

Elementis DAPRO DF 677 Defoamer is a silicone-free, water-dispersible antifoam agent from Elementis’ DAPRO DF series. Designed for high-shear aqueous systems like coatings and adhesives, it delivers rapid foam knockdown and lasting suppression without affecting gloss or substrate wetting. Its non-silicone formulation avoids compatibility issues and surface defects.

Features Of Elementis DAPRO DF 677 Defoamer

  1. Highly effective silicone-based defoamer for rapid foam knock-down and long-term foam suppression.

  2. Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.

  3. Low dosage efficiency—typically effective at 0.05–0.3 wt% on total formulation.

  4. Thermally stable up to 120°C, supporting high-temperature processing conditions.

  5. Non-yellowing and non-staining, preserving clarity and color integrity in final coatings and adhesives.

Typical Applications Of Elementis DAPRO DF 677 Defoamer

  1. Architectural and industrial waterborne paints and coatings.

  2. Adhesives and sealants, especially pressure-sensitive and construction-grade formulations.

  3. Textile printing pastes and pigment dispersions.

  4. Construction chemicals, including cementitious tile adhesives and grouts.

  5. Water-based inks and functional coatings for packaging substrates.
