Highly reactive liquid 4,4'-diphenylmethane diisocyanate (MDI) with low viscosity for excellent processability in mixing and dispensing systems.
Consistent monomeric MDI content ensures reliable reactivity and predictable cure kinetics in polyurethane formulations.
Low volatility and reduced vapor pressure compared to pure monomeric MDI, enhancing workplace safety and handling stability.
Optimized for ambient- and elevated-temperature curing, enabling flexibility in production line design and cycle time reduction.
Compatible with a broad range of polyols—including polyester, polyether, and polycarbonate types—supporting formulation versatility.
Reaction injection molding (RIM) and structural RIM (SRIM) for automotive interior and exterior components.
Cast elastomer systems used in industrial rollers, mining screens, and high-wear mechanical parts.
Flexible and semi-rigid polyurethane foams for seating, bedding, and acoustic insulation applications.
Adhesives and sealants requiring fast green strength development and excellent substrate bonding.
Coating systems for protective and decorative finishes on metal, wood, and composite substrates.
