Lupragen® BisDMAPU is a new low-emission catalyst designed for flexible polyurethane (PU) foam applications. Lupragen BisDMAPU (chemical name: 1,3-Bis[3-(dimethylamino)propyl]urea, CAS 52338-87-1) is a balanced PU catalyst that supports both gelling and blowing reactions, ensuring reliable, high-quality foam formation and dimensional stability. With its low volatility and low odor, the catalyst can help manufacturers reduce volatile organic compound (VOC) emissions from finished foam products, making it suitable for applications that must meet low-VOC standards. Designed primarily to produce flexible PU foams, including slabstock and molded foams used in furniture, mattresses and automotive interiors, Lupragen BisDMAPU also finds use in other applications, such as reactive hotmelt polyurethane adhesives, two‑component epoxy systems and cationic polymers. With its distinct reactivity profile and unique chemical properties, it complements this company’s Lupragen N 208 catalyst family, which was launched in December 2025. — BASF SE, Ludiwgshafen, Germany
