Additional information

The rate constant of the OH radical sensitized indirect photodegradation of isophorone diisocyanate corresponds to a half-life of 1.8 days at a 24 hour mean OH radical concentration of 500,000 molecule/cm³, which is typical of Central Europe. A preliminary hydrolysis test resulted in a dissipation half-life of 0.84 hours (approx. 50 minutes) at 23 °C.
