Mondur MRS is a high functionality polymeric diphenylmethane diisocyanate (pMDI) with an enhanced 2,4’-MDI isomer content.
Mondur MRS 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 product by customer, when stored in closed original containers and stored under the recommended conditions.
