Persistence and Degradability
Data for Component: Diphenylmethane Diisocyanate, isomers and homologues
In the aquatic and terrestrial environment, material reacts with water forming predominantly
insoluble polyureas which appear to be stable. In the atmospheric environment, material is
expected to have a short tropospheric half-life, based on calculations and by analogy with
related diisocyanates.
