Molecular Foundation & Catalytic Selectivity
Molecular structure of Ming Xu Chem’s MXC-DMI (CAS 1739-84-0), a potent imidazole-based curing catalyst.
The fundamental structure of MXC-R70 defines its exceptional stability and precise control over PU formulations:
-
Heterocyclic Imidazole Ring: Unlike traditional amine structures, the core imidazole ring provides a moderate basicity that perfectly balances the blowing and gelling reactions, ensuring uniform cell growth.
-
High Reactive Potential: With a robust Hydroxyl Value (542 mg/KOH/g), it delivers excellent reactive potential within the polyol premix, allowing for lower loading levels to achieve the desired catalytic effect.
Surface Cure & Adhesion Performance
MXC-R70 is a high-performance liquid catalyst formulated for precise cross-linking and optimal mechanical properties in PU systems.
For continuous line and spray foam manufacturers, MXC-R70 acts as a powerful post-curing accelerator to resolve common structural defects:
-
Eliminates Surface Friability: It is specifically engineered to drive the final stages of the isocyanate reaction, completely resolving the surface brittleness (friability) often caused by rapid demolding.
-
Enhanced Substrate Adhesion: By creating a tougher and fully cured polymer matrix at the foam interface, it drastically improves bonding strength to substrates like metal or wood.
-
HFO System Compatibility: It works exceptionally well in modern HFO blowing agent systems and water co-blown systems, maintaining a smooth rise profile and superior dimensional stability.
Process Efficiency & Operational Stability
We focus on delivering high-performance solutions that seamlessly integrate into your automated factory equipment and improve workplace safety:
-
Winter-Ready Stability: Featuring a freezing point below -10°C, this catalyst remains highly stable and prevents crystallization during cold-weather storage and transportation.
-
Ultra-Low Viscosity: At just 10 mPa.s, its water-like fluidity ensures effortless pumping, perfect miscibility, and highly accurate dosing in high-pressure foaming machines.
-
Low-Odor Profile: Compared to conventional volatile amines, MXC-R70 exhibits a significantly lower odor profile, improving the working environment on the factory floor and the final product’s market appeal.
