Desmodur® 44MC LIQUID

Desmodur® 44MC LIQUID by Covestro is a monomeric diphenylmethane 4,4' diisocyanate (MDI) with a molecular weight of 250 [g/mol]. It is a white to pale yellow solid. It is sensitive to moisture and reacts with water to form insoluble urea derivatives and carbon dioxide. Contact with air, especially if accompanied by simultaneous exposure to light, accelerates yellowing. It is therefore advisable to store liquid under dry nitrogen. It is sensitive to heat and likely to dimerization. Desmodur® 44MC LIQUID is used to produce polyurethanes.
