Highly reactive aromatic isocyanate based on diphenylmethane diisocyanate (MDI) with optimized viscosity for easy handling and metering.
Low monomeric MDI content (< 0.5 %), supporting improved occupational safety and regulatory compliance.
Excellent compatibility with polyols and amine-terminated resins, enabling broad formulation flexibility in two-component systems.
Delivers outstanding mechanical properties—including high tensile strength, abrasion resistance, and thermal stability—in cured elastomers and coatings.
Consistent batch-to-batch quality ensured by Covestro’s stringent GMP-aligned manufacturing standards.
Reaction injection molding (RIM) and reinforced RIM (RRIM) for automotive structural parts and exterior trim.
High-performance polyurea and hybrid polyurethane/polyurea coatings for industrial flooring, tank linings, and corrosion protection.
Cast elastomer systems used in mining screens, pump housings, and heavy-duty rollers.
Adhesives and sealants requiring rapid green strength development and long-term durability under dynamic stress.
3D printing resins and specialty binders for advanced composite manufacturing.
