Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Based on the physico-chemical properties of Hexamethylene diisocyanate, trimers, reaction products with 2-hydroxyethyl acrylate (CAS 162492-01-5), such as low water solubility (< 0.54 mg/L, 20 °C), low potential for volatilization (vapor pressure = 8.1E-08 hPa, 20 °C) and the estimated log Koc (5.61 – 15.09, KOCWIN v2.00, MCI; 2.73 - 2.84 KOCWIN v2.00, log Pow method), the substance is expected to partition mainly to the soil and sediment compartment. Since the substance is not readily biodegradable (0% in 28 d, OECD 301 B) a significant decrease of substance concentrations is not expected to occur via degradation in sewage treatment plants (STP). However, due to potential adsorption to sewage sludge the release via STP effluent might be limited.
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.
