General Characterization

Mondur 541-Light is an aromatic polymeric isocyanate based on diphenylmethane-diisocyanate (MDI).

Storage Conditions

Mondur 541-Light polyisocyanate must be stored in tightly closed containers and protected from moisture. Processability of this material can be adversely affected by contamination. It will react slowly with water to form polyureas and liberate carbon dioxide gas, which may cause sealed containers to expand and rupture. Recommended storage temperatures are 10° to 30°C (50° 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.
