DOWSIL 56 Additive is a high-performance silicone-based defoamer, specialized in eliminating microfoams in solvent-based systems while enhancing leveling. Its alkyl-modified polysiloxane structure (100% active) maintains stability at high temperatures (≤150°C) and across broad pH ranges, reducing surface tension to ≤25 mN/m. This not only resolves bubble retention in curtain coating and metallic paints but also boosts gloss by 15%-20% and improves abrasion resistance. Optimized for pigment orientation, it ensures no compromise on recoatability, meeting both eco requirements (VOC<50g/L) and high-efficiency industrial needs.
Micro-Foam Targeting: Rapidly removes micron-sized bubbles in solvent coatings, minimizing pinholes and craters.
Leveling & Gloss Enhancement: Lowers surface tension for superior flow, boosting gloss in high-gloss wood and industrial coatings.
Robust Stability: Performs reliably in pH 2-12 and high-temperature baking processes.
Wide Compatibility: Works with acrylic, epoxy, and PU resins; does not interfere with recoating.
Cost Efficiency: Delivers results at low dosages (0.05%-0.5%), cutting overall costs.
Wood Coatings: Eliminates bubbles in solvent-based varnishes for curtain coating (0.05%-0.5% dosage).
Industrial Coatings: Enhances scratch resistance and metallic pigment alignment in coil/auto OEM paints.
Printing Inks: Improves leveling in solvent flexo inks, reducing print streaks (0.05%-0.1%).
Plastic Coatings: Boosts gloss and wear resistance for engineering plastics (e.g., PC, ABS).
