Haimins DAPRO DF677 Defoamer

Haimins DAPRO DF677 is a high-efficiency water-based defoamer designed for water-based inks, printing coatings, and industrial paints. It adopts emulsified polysiloxane technology to deliver efficient foam control in aqueous systems, excelling in both immediate defoaming and long-term antifoaming performance. With strong compatibility across various formulations, it maintains long-lasting stability while minimizing impact on product transparency—making it ideal for applications requiring visual clarity (such as water-based adhesives). Easily dispersible in water, it can be added at different production stages with a recommended dosage of 0.1–0.5%, ensuring reliable bubble-free results for water-based coatings, inks, and other waterborne systems.

Product Information of Haimins DAPRO DF677 Defoamer

  1. Core Technology: Water-based formulation leveraging emulsified polysiloxane technology, specifically optimized for efficient foam control in aqueous systems.

  2. Dual Foam Control Performance: Excels in both defoaming (eliminating existing foam) and antifoaming (preventing new foam formation) capabilities, paired with long-lasting stability to avoid re-foaming during production or storage.

  3. Transparency Preservation: Minimizes negative impact on the transparency of final products, a key advantage for applications like water-based adhesives or clear coatings that require high visual clarity.

  4. User-Friendly Design: Easily dispersible in water without requiring complex mixing processes; flexible addition timing (compatible with different production stages) enhances operational convenience.

Areas of Application of Haimins DAPRO DF677 Defoamer

  1. Water-Based Inks: Suitable for water-based ink systems (e.g., flexographic inks, gravure inks), controlling foam during ink manufacturing and printing processes to prevent defects like uneven color, ink splashing, or pinholes in prints.

  2. Printing Coatings: Ideal for printing-related coatings (e.g., overprint varnishes, substrate pre-coatings), ensuring smooth, bubble-free film formation and preserving coating gloss/transparency.

  3. Industrial Paints: Applied in water-based industrial paints (e.g., metal coatings, plastic coatings), eliminating foam generated during high-speed stirring or spraying to maintain paint film integrity and surface quality.
