Evonik TEGO Flow 425 is a high-performance leveling agent specifically engineered for radiation-cured varnishes and plastic coatings. It delivers superior flowability and recoatability while maintaining exceptional clarity (ΔHaze <0.5%) even at elevated temperatures (up to 80°C).
Surface Optimization: Reduces craters by >90% and improves DOI by 15-25%
Enhanced Lubricity: Lowers COF to 0.20-0.28 for better anti-blocking
Multi-layer Performance: Maintains >93% intercoat adhesion after multiple applications
Broad Compatibility: Effective in 10-90% solids water/UV/solvent systems
Optical Clarity: Minimizes haze formation in clear coat formulations
Wood Coatings: High-end furniture finishes (90+° gloss at 0.2-0.7% dosage)
Auto Refinish: Prevents cratering in 2K systems (spray/roller application)
Industrial Coatings: Flow promoter for epoxy/acrylic coatings (curtain/roll)
UV Inks: Leveling enhancer for radiation-curable printing inks
