Description of key information

The QSAR calculated rate constant for the OH sensitized photodegradation of Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, caprolactam-blocked (surrogate: blocked trimer) is approximately 112.1E-12 cm3/(molecule * s). At 500,000 OH radicals / cm3, this corresponds to a half-life of 3.4 hours.

Key value for chemical safety assessment

Half-life in air:
3.4 h
Degradation rate constant with OH radicals:
