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.
Core Technology: Water-based formulation leveraging emulsified polysiloxane technology, specifically optimized for efficient foam control in aqueous systems.
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.
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.
User-Friendly Design: Easily dispersible in water without requiring complex mixing processes; flexible addition timing (compatible with different production stages) enhances operational convenience.
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.
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.
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.
