HDI asymt. trimer hydrolyses rapidly in the presence of water yielding a complex mixture of oligomeric and polymeric urea derivatives which are non-soluble in water. Due to the rapid hydrolysis of HDI asymt. trimer, a transport of the substance between environmental compartments is unlikely.Consequently, a calculation of the Henry Law Constant and of the distribution between the environmental compartments according to the Mackay fugacity model level 1 or 3 is not suitable.
