In today’s polyurethane industry, performance, safety, and sustainability are key drivers for innovation. As regulations tighten and manufacturers increasingly seek to eliminate heavy metals from their formulations, MXC-B20 emerges as a next-generation polyurethane catalyst that meets these demands without compromising performance.
What Is MXC-B20?
MXC-B20 is a bismuth metal carboxylate catalyst developed as a high-performance alternative to traditional tin-based catalysts such as dibutyltin dilaurate. Equivalent to DABCO MB20, MXC-B20 is designed to work synergistically with tertiary amine catalysts to promote polyurethane reactions and curing.
Unlike conventional catalysts that may emit strong odors or contain hazardous metals like mercury, lead, or tin, MXC-B20 is a low-odor, low-volatility, and environmentally conscious option, helping manufacturers achieve both technical and regulatory goals.
Key Features of MXC-B20
✅ Non-Toxic: Free from mercury, lead, and dibutyltin.
✅ Low Odor: Ideal for formulations where odor control is critical.
✅ Low Volatility: Enhances workplace safety and product stability.
✅ Compatible with Various Systems: Works well with common rigid and flexible foam polyols.
✅ Optimized Reaction Profile: Offers front-end delay with strong back-end curing, ideal for complex formulations.
Application Areas
MXC-B20 is a versatile catalyst suited for a wide range of polyurethane foam systems, including:
