Description of key information

Additional information

Releases into the environment may occur during production of 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl isocyanate homopolymer, during formulation, and during use of the substance or its formulations as an intermediate or as a crosslinker in various applications.

Distribution modelling is not possible because due to rapid hydrolysis the water solubility as a key input datum cannot be measured. Henry’s Law constant and adsorption / desorption behaviour also cannot be determined because of hydrolysis. It is expected that immobile polymers will be formed upon entry into the environment as soon as the substance reaches the hydrosphere or other wet compartments. Environmental distribution of the substance itself is inhibited by its rapid hydrolysis, and environmental distribution of the hydrolysis products is inhibited by their negligible vapour pressure and water solubility.
