General Information :Hydrophilic isocyanates are very sensitive to moisture and react with water to form carbon dioxide and water-insoluble urea. It must therefore be stored in airtight containers. Water in all forms (humid air, solvents, wet containers) must be prevented because of the dangerous build-up of pressure caused by the production of carbon dioxide. High temperature storage will cause a slight increase in viscosity and color.
