Aliphatic HDI-based polyisocyanate with excellent UV stability and color retention.
Low monomer content (<0.5% free HDI) for enhanced occupational safety and regulatory compliance.
Optimized viscosity (≈1,800–2,200 mPa·s at 25°C) enabling easy handling and compatibility with standard coating equipment.
High functionality and reactivity with hydroxyl-terminated resins, delivering rapid cure kinetics at ambient or low-bake conditions.
Excellent compatibility with acrylic, polyester, and polyol-based resin systems without phase separation.
Automotive clearcoats and basecoats requiring long-term gloss retention and weather resistance.
Industrial maintenance coatings for metal and plastic substrates in transportation and construction sectors.
High-performance can and coil coatings demanding film hardness, flexibility, and chemical resistance.
Precision optical and electronic encapsulation coatings where clarity and low yellowing are critical.
