Advanced Trimerization Catalyst for Flame-Retardant PIR Systems
MXC-15 (Potassium Octoate Solution) is a premium, highly specialized metal carboxylate catalyst. Engineered specifically to drive the trimerization of isocyanates, it is the industry standard for manufacturing polyisocyanurate (PIR) rigid foams that require exceptional thermal insulation, high structural integrity, and rigorous fire safety compliance
Molecular Architecture & Trimerization Core
The fundamental chemical design of MXC-15 is tailored to construct robust and heat-resistant polymer networks:
-
Potassium-Driven Trimerization: Unlike standard amine catalysts, the highly active potassium core acts specifically to promote the formation of stable isocyanurate rings, fundamentally altering and strengthening the polymer matrix.
-
Reactive DEG Carrier: Diluted in Diethylene Glycol (DEG), it maintains a stable liquid state while the DEG acts as a reactive diluent, chemically binding into the polyurethane network without migrating or causing long-term degradation.
Fire Safety & Thermal Insulation Performance
For manufacturers of building materials and commercial insulation, MXC-15 resolves the critical challenge of meeting strict global flammability regulations:
-
Superior Flame Retardancy: The dense polyisocyanurate (PIR) network generated by this catalyst exhibits exceptional heat resistance, drastically improving the fire safety classification of your rigid insulation panels.
-
Enhanced Dimensional Stability: It ensures a highly cross-linked, uniform cell morphology. This prevents foam shrinkage and provides outstanding long-term compressive strength even under extreme temperature fluctuations.
Process Efficiency & Formulation Control
We prioritize strict quality parameters to guarantee predictable performance and seamless integration into your large-scale manufacturing operations:
-
Optimized Liquid Dynamics: Formulated as a clear to light yellow liquid with a controlled viscosity (Max. 6000 cps at 25°C), it allows for effortless pumping and precise machine metering in high-speed laminators.
-
Stable Reaction Profile: With a strictly controlled alkaline profile (pH Min. 9.0) and optimal water content (3.1-3.5%), it delivers highly consistent rise times and predictable curing profiles, preventing costly production delays.
-
Amine Synergy: It works flawlessly in conjunction with standard tertiary amine co-catalysts, giving technicians the ultimate flexibility to fine-tune the balance between the initial foam expansion and final cross-linking phases.
