Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is primarily used as bonding agent in polymers and is therefore chemically reacted/stabilised within finished articles. Although moderately water soluble (5 mg/mL), as the material is chemically reacted, it is not expected to leach from finished articles into surface water, soil or ground water.
The vapour pressure of the substance is very high (18.5 Pa) and the modelled Henry’s law constant is 723 Pa m3/mol. This indicates that the substance is highly volatile and upon release, it will immediately distribute into the atmospheric compartment. Losses to the atmospheric compartment could also occur during manufacture, however as manufacture takes place outside EU, this stage is not taken into consideration in the present dossier.
The primary route of removal from the atmosphere is through the gas-phase reaction between ozone or photochemically produced hydroxyl radicals and the substance. The modelled DT50 of 8.629 h shows that removal from the atmosphere is rapid, therefore the material is not expected to accumulate in this compartment.
In conclusion, the predicted concentrations in the terrestrial and aquatic compartments based on the proposed uses are close to zero. The rapid degradation predicted in the atmospheric compartment indicates that the substance will be removed rapidly from this compartment within a short duration.
Additional information
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.
