According to a Mackay Level I model calculation, the main target compartments for Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, caprolactam-blocked will be sediment (50.1 %) and soil (49.5 %). The calculated Henry’s Law constant of <= 0.057 Pa m³/mol at 20 °C indicates very low volatility of Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, caprolactam-blocked from surface waters. With a log Koc of 6.1 l/kg, a „very high“ sorption potential of the substance to soil or sediment organic matter is expected. (Blume scale). Very low release rates are expected in association with very high elimination via adsorption in waste water treatment plants.
