Premium Eco-Friendly Metal Catalyst for Advanced Curing Profiles
MXC-B20 (Bismuth Neodecanoate) is a highly specialized, non-toxic organometallic catalyst. Engineered with a strictly controlled bismuth content of 19.5-20.5%, it serves as a powerful and environmentally friendly replacement for traditional heavy-metal catalysts. It is the premier choice for manufacturers demanding precise curing control in rigid foams, elastomers, and sophisticated molded systems
Molecular Architecture & Eco-Friendly Design
The fundamental design of MXC-B20 directly addresses the industry’s shift towards sustainable and non-toxic chemical manufacturing:
Non-Toxic Organobismuth Core: As a specialized bismuth carboxylate, it serves as a highly effective, low-toxicity alternative to traditional organotin catalysts (such as DBTDL).
Heavy-Metal Free Compliance: It is entirely free of mercury, lead, and dibutyltin compounds. This ensures your final products comply with increasingly strict global environmental regulations and occupational health standards without sacrificing catalytic performance.
Dynamic Curing Profile & Process Control
For production managers handling complex molds or high-speed manufacturing lines, MXC-B20 resolves critical processing bottlenecks:
Delayed Viscosity Build: It provides a highly controlled “front-end” induction period. This extended pot life ensures excellent liquid flowability, allowing the reacting polyurethane mixture to completely fill intricate molds before gelation begins.
Strong Back-End Cure: Once the reaction temperature rises, it triggers an exceptionally rapid and thorough back-end cure. This dramatically improves the “green strength” of the matrix, significantly reducing demolding times and boosting factory output.
Process Efficiency & Formulation Stability
We maintain rigorous quality control parameters to safeguard your formulation integrity and ensure safe industrial handling:
Strict Moisture Control: With a guaranteed maximum water content of just 0.5%, it minimizes parasitic side reactions and prevents the degradation of the catalyst, ensuring a highly predictable reaction profile.
Effortless Liquid Integration: Supplied as a clear, light yellow liquid, it is fully miscible with common rigid and flexible foam polyols, allowing for seamless integration into your existing pre-mix tanks.
Low-Volatility & Low Odor: It features a minimal odor profile and extremely low volatility, drastically improving the working environment on the factory floor and reducing final product emissions.
