Introduction
Lupranate®M20S is a polymeric MDI with a functionality of approximately 2.7. Lupranate M20S is suitable for the production of rigid insulation foams by molding, spraying, and frothing. It is also used for rigid and semi-flexible integral skin foams, adhesives, sealants, elastomers, and high-resiliency flexible foams. Inlow catalyzed rigid urethane formulations, the foam rise time can be lengthened by 20-30%. The slower reactivity can be advanta- geous in applications such as large rigid foam panels or molded flexible foams.

Shelf Life
The shelf life of Lupranate M20S is six months if the temperature is maintained at 15-35°C and moisture is excluded.
Storage
Lupranate M20S is supplied in tank cars, tank trucks, and drums. Once a container has been opened, care should be taken to exclude
moisture. The most favorable temperature for storage is 15-35°C. If stored at higher temperatures, or if moisture is not excluded, an
undesirable increase in viscosity will occur. Below 15°C, the product becomes difficult to pump and pour. Below 0°C, crystallization may
occur.
Warning
These products can be used to prepare a varietyofpolyurethaneproducts.Polyurethanesare organic materials and must be considered
combustible.
