According to a Mackay Level I model calculation, the main target compartments for Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, acetone oxime-blocked will be sediment (48.6 %) and soil (48.1 %). The calculated Henry’s Law constant of 1.7E-9 Pa m³/mol at 20 °C indicates very low volatility of Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, acetone oxime-blocked from surface waters. With an adsorption coefficient (Koc) of log Koc = 4.4 for soil and log Koc = 4.5 for sewage sludge determined with the HPLC method the sorption potential to soil or sediment organic matter is expected to be very high (Blume scale).
