Haimins DAPRO AP7010 Defoamer

DAPRO AP7010 is a water-based defoaming chemical auxiliary agent specialized for polyurethane paint, color topcoats, and varnishes. It is formulated as a VOC-free, mineral oil-based defoamer blended with hydrophobic silica, and is also well-suited for waterborne decorative paints and coatings. This defoamer delivers reliable foam control across critical production phases—both grinding (reducing air entrainment from high-speed mixing) and let-down (preventing re-foaming during formulation adjustment)—with rapid bubble-breaking action even at low concentrations. Notably, it excels in semi-gloss and high-gloss paint systems, while its strong compatibility and long-term stability ensure consistent performance in aqueous systems (paints, coatings, inks). At a recommended dosage of 0.3–1.0% by total weight, it maintains efficient antifoaming properties without compromising the integrity of end products.

Product Information of Haimins DAPRO AP7010 Defoamer

  1. Eco-Friendly & High-Performance Composition: VOC-free, mineral oil-based formula infused with hydrophobic silica, meeting low-emission standards and delivering targeted foam control for waterborne systems.

  2. Dual-Phase Foam Management: Effectively controls foam during both the grinding phase (minimizes air trapped during pigment/dispersant mixing) and let-down phase (stops re-foaming when diluting or adding additives), covering the full production cycle of paints/coatings.

  3. Gloss-Optimized Performance: Excels in semi-gloss and high-gloss waterborne systems (e.g., polyurethane topcoats, varnishes), breaking bubbles rapidly at low concentrations without dulling the desired gloss finish or causing surface defects.

Areas of Application of Haimins DAPRO AP7010 Defoamer

  1. Polyurethane Paint & Topcoats: Ideal for water-based polyurethane paint and color topcoats, eliminating foam during production and application to ensure smooth, bubble-free surfaces—critical for maintaining the paint’s durability and aesthetic appeal.

  2. Varnishes: Specifically effective for water-based varnishes (e.g., wood varnishes, metal varnishes), preventing foam-induced pinholes or craters while preserving the varnish’s high-gloss or semi-gloss finish.

  3. Waterborne Decorative Paints: Suitable for waterborne decorative paints (interior/exterior wall paints, furniture paints), applied in grinding/let-down phases to maintain paint texture and avoid foam-related defects like “fish-eyes.”
