Performance Benefits
In low-catalyzed rigid urethane formulations, Lupranate M20S extends foam rise time by 20-30%. This slower reactivity provides significant advantages for large rigid foam panels and molded flexible foams, allowing better process control and improved final product quality.
Storage & Handling
- Available in tank cars, tank trucks, and drums
- Optimal storage temperature: 15-35°C
- Exclude moisture after container opening to prevent viscosity increase
- Avoid temperatures below 15°C to prevent pumping difficulties
- Prevent crystallization by maintaining temperatures above 0°C
- Shelf life: 6 months at 15-35°C with moisture exclusion
Safety Information
Lupranate M20S is used to prepare various polyurethane products. As organic materials, polyurethanes must be considered combustible. Follow all safety protocols and handling guidelines during use.
