Haimins DAPRO DF661 Defoamer

Haimins DAPRO DF661 is a high-efficiency water-based defoamer tailored for industrial coatings, waterborne paints, and metal baking varnishes. As a VOC-free, mineral oil-based formulation blended with hydrophobic silica, it also suits waterborne decorative paints and coatings. This defoamer delivers reliable foam control across critical production phases—both grinding and let-down—with rapid bubble-breaking action even at low concentrations, particularly excelling in semi-gloss and high-gloss systems. Boasting strong compatibility and long-term stability, it ensures consistent performance in aqueous systems (paints, coatings, inks) while preserving product integrity, with a recommended dosage of 0.3–1.0% by total weight.

Product Information of Haimins DAPRO DF661 Defoamer

  1. Eco-Friendly Composition: VOC-free, mineral oil-based formula infused with hydrophobic silica, meeting low-emission requirements and suitable for environmentally conscious applications.

  2. Dual-Phase Foam Control: Effectively manages foam during both the grinding (reduces air entrainment from high-speed mixing) and let-down (prevents re-foaming when diluting or adjusting formulations) phases of paint/coating production.

  3. Gloss Compatibility: Excels in semi-gloss and high-gloss waterborne systems (e.g., metal baking varnishes), breaking bubbles rapidly at low concentrations without compromising the desired gloss finish.

Areas of Application of Haimins DAPRO DF661 Defoamer

  1. Industrial Coatings: Ideal for water-based industrial coatings (e.g., machinery coatings, equipment finishes), controlling foam during production and application to ensure smooth, defect-free (no pinholes/craters) coating films.

  2. Waterborne Paints: Suitable for waterborne decorative paints and general waterborne paints, especially semi-gloss and high-gloss varieties—applied in grinding/let-down phases to maintain paint texture and finish quality.

  3. Metal Baking Varnishes: Specifically effective for water-based metal baking varnishes, eliminating foam that could cause surface flaws during baking, while preserving the varnish’s high-gloss appearance and adhesion to metal substrates.
