High reactivity with polyols and amines, enabling rapid gelation and short demold times.
Low monomeric MDI content (< 0.5 wt%), enhancing workplace safety and regulatory compliance.
Excellent hydrolytic stability due to controlled uretonimine modification and inhibited self-polymerization.
Tailored viscosity (150–250 mPa·s at 25°C) for precise metering and uniform dispersion in multi-component systems.
Consistent batch-to-batch performance supported by Tosoh’s ISO 9001-certified manufacturing and strict QC protocols.
High-performance rigid polyurethane insulation foams for refrigeration and building envelope applications.
Reaction injection molding (RIM) and reinforced RIM (RRIM) components in automotive interior and structural parts.
Cast elastomer systems requiring fast cure cycles and high abrasion resistance, such as industrial rollers and mining screens.
Two-component polyurethane adhesives and sealants for demanding transportation and construction bonding.
Coating resins for protective industrial topcoats where chemical resistance and rapid through-cure are critical.
