High-reactivity aromatic diisocyanate based on methylene diphenyl diisocyanate (MDI) for fast-cure polyurethane systems.
Low volatility and reduced monomeric MDI content compared to standard 4,4′-MDI, enhancing workplace safety and handling stability.
Excellent compatibility with polyether and polyester polyols, enabling broad formulation flexibility across rigid and semi-rigid foams.
Consistent reactivity profile ensures reproducible processing behavior in continuous slabstock and molded foam production.
Optimized for use in moisture-cured and prepolymer-based systems requiring balanced pot life and demold time.
Rigid polyurethane insulation foams for refrigeration and building envelope applications.
Semi-rigid automotive seating and headrest foams requiring high resilience and dimensional stability.
Industrial elastomer castings including rollers, wheels, and mining screens.
Adhesives and sealants where rapid green strength development is critical.
Coatings and binders for composite wood products and foundry core applications.
