Gradient Defoaming: Equipped with a 2 μm silicone-silica gradient system, it eliminates foam in 3 seconds (per DIN 53941 standards), ensuring efficient and targeted foam control.
Non-Migrating Formula: Leaves zero residue after drying, compliant with ASTM D3274, avoiding contamination or surface defects in end products.
Shear Universality: Maintains stability under high-shear conditions, including ≥15 m/s bead milling and ≤200 rpm mixing, ensuring consistent performance in diverse processing workflows.
Acid Resistance: Retains activity in pH 3 metal pretreatment coatings, adapting to acidic formulation environments.
Heavy-Duty Topcoats: Achieves a DOI (Distinctness of Image) ≥88 in epoxy systems with ≥65% solids, enhancing the finish quality of durable coatings.
Flexible Packaging Inks: Reduces trailing on NY (nylon) film at speeds ≥450 m/min, ensuring smooth, high-speed printing.
Paper Varnishes: Delivers ≥95 GU (Gloss Unit) gloss in acrylic formulations with ≥40% solids, enhancing the visual appeal of paper finishes.
Anti-Corrosive Primers: Controls zinc settlement to ≤0.5% in zinc-rich formulations with ≥80% zinc content, maintaining primer integrity and anti-corrosive performance.
