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.
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.
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.
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.
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.
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.
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.”
