General Characterization

Mondur MR 5 is a low to medium functionality polymeric diphenylmethane diisocyanate (pMDI) containing a relatively high level of pure (monomeric) MDI.

Storage Conditions

Mondur MR 5 isocyanate must be stored in tightly closed containers and protected from contamination with moisture and foreign materials, which can adversely affect processing. It will react slowly with water to form polyureas and liberate carbon dioxide gas, which may cause sealed containers to rupture. Storage temperatures should be maintained at 24° to 30°C (75° to 86°F).
The shelf life is six months after receipt of material by customer, when stored in sealed original containers under conditions stated above.
