High-purity 4,4'-diphenylmethane diisocyanate (MDI) with minimal monomeric impurities for consistent reactivity and reduced VOC emissions.
Excellent hydrolytic stability and low moisture sensitivity, enabling extended pot life and reliable processing in ambient conditions.
Precision-engineered for controlled crosslinking kinetics—ideal for one-component polyurethane systems requiring balanced cure speed and workability.
Enables formulation of high-performance elastomers and coatings with superior mechanical strength, abrasion resistance, and chemical durability.
Compatible with standard polyol blends and catalysts, supporting seamless integration into existing PU manufacturing infrastructure.
Single-component moisture-curing polyurethane adhesives for automotive assembly and structural bonding.
High-resilience elastomeric coatings for industrial flooring, tank linings, and corrosion protection.
Castable polyurethane elastomers used in mining screens, conveyor pulleys, and heavy-duty wear parts.
Reaction injection molding (RIM) systems for automotive trim, bumpers, and energy-absorbing components.
Sealants and joint fillers in construction applications requiring long-term UV stability and weather resistance.
