Haimins DAPRO DF52 is a high-efficiency, mineral oil-free water-based defoamer specialized for water-based inks, flexographic printing, and paper coatings. It adopts emulsified polysiloxane technology to deliver efficient foam control in aqueous systems, excelling in both immediate defoaming (eliminating existing foam) and long-term antifoaming (preventing new foam formation) 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 & Composition: Water-based formulation leveraging emulsified polysiloxane technology; uniquely mineral oil-free, meeting strict requirements for low-residue or oil-sensitive applications (e.g., paper coatings, food-contact compatible inks).
Dual Foam Control Performance: Excels in both defoaming and antifoaming capabilities, with long-lasting stability to avoid re-foaming during production, storage, or application—even in dynamic processes like flexographic printing.
Transparency Preservation: Minimizes negative impact on the transparency of final products, a key advantage for clear paper coatings, transparent water-based inks, or water-based adhesives that rely on visual clarity.
Water-Based Inks: Ideal for water-based inks (e.g., flexographic inks, gravure inks for paper/film substrates), controlling foam during ink manufacturing (high-speed stirring) and printing (roll-to-roll processing) to prevent defects like uneven color, ink splashing, or pinholes in prints.
Flexographic Printing: Specifically optimized for flexographic printing processes, where it eliminates foam in inks or wetting agents to ensure consistent ink transfer, sharp print edges, and no foam-induced interruptions to the continuous printing line.
Paper Coatings: Suitable for water-based paper coatings (e.g., surface sizing coatings, decorative paper topcoats), preventing foam from forming during coating application (blade coating, rod coating) to maintain a smooth paper surface and avoid coating defects (e.g., spots, air bubbles).
