Highly stable aliphatic trimer structure ensures excellent storage stability and low volatility.
Low free TDI monomer content (< 0.1 wt%) meets stringent occupational health and environmental compliance requirements.
Consistent reactivity profile enables predictable gel times and robust crosslinking in polyurethane systems.
Excellent compatibility with polyester and polyether polyols, facilitating homogeneous formulation without phase separation.
Delivers superior chemical resistance and mechanical toughness in cured thermoset coatings and adhesives.
High-performance two-component polyurethane coatings for industrial metal protection.
Automotive refinish clearcoats requiring rapid cure, gloss retention, and mar resistance.
Flexible and rigid foam systems where controlled reactivity and low fogging are critical.
UV-resistant elastomeric sealants and construction joint fillers.
Polyurethane-based textile and leather finishing resins for durable soft-touch effects.
