Description of key information
Additional information
The direct and indirect exposure of the aquatic compartment is unlikely because HDI Uretdion hydrolysis completely in water within far less than 24 hours at environmental relevant concentrations.
For this reason, an experimental study is not useful, and calculated values were used. Bioconcentration factors (BCF) of 457 and 143 L/kg wet-wt for the main component HDI Uretdion and its corresponding diamine were obtained (Currenta, 2014e). Also the corresponding diamine of HDI Uretdion with a bioconcentration factor of 143 L/kg wet-wt does not have high bioaccumulation potential (Currenta, 2014f).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
