MONDUR 489

Mondur 489 is a high-functionality polymeric diphenylmethane-diisocyanate (PMDI) used in manufacturing applications. Mondur 489 polyisocyanate provides benefits for material properties due to its NCO content of 30.0-31.4% and viscosity range of 610-790 mPas. The dark brown liquid formulation exhibits specific advantages for developing high strength at low temperatures and resistance to chemicals/solvents. Mondur 489 is commonly employed as a curing agent to produce composite laminates/parts with enhanced mechanical characteristics. Its reactivity enables crosslinking polymers for demanding performance needs. Proper storage of Mondur 489 between 10-30°C helps maintain stability for continuous processing over its six month shelf life. The product supports robust and durable end products across various industries.
