Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Stability
Hydrolysis
The hydrolysis of Sika Hardener MI in different media (ultra-pure water, aprotic and protic organic solvents like acetonitrile and methanol) and the stability of Sika Hardener MI's degradation product (Aldehyde M) in water and aqueous buffer solutions (OECD and ISO medium) at room temperature were investigated using LC/MS and LC/MS/MS, respectively. Measurements revealed a very fast hydrolysis of Sika Hardener MI in water and water-based media (t1/2 < 0.5 minutes in water). The degradation products of the hydrolysis of Sika Hardener MI are 2,2-dimethyl-3-(morpholin-4-yl)propanal (Aldehyde M) and 3-Aminomethyl-3,5,5-trimethylcyclohexylamine.
Biodegrdation
Biodegradation: screening test
The ready biodegradability of the test item was assessed over a 28 day period in a closed bottle test (EU method C 4-E). The test material attained up to 0 % biodegradation after 28 days whereas the reference substance (Sodium benzoate) was 60.5 % degraded 28 days. These results indicate that the test item cannot be classified readily biodegradable under conditions of the test.
Transport and distribution
Adsorption / desorption
The performance of the adsorption/desorption screening test is scientifically unjustified. Due to rapid decomposition (hydrolysis) of the test substance upon contact with water, measurement of the adsorption behaviour of the test substance is technically not feasible.
The log Koc was calculated using KOCWIN v2.00 via MCI and log Kow method as part of EPISuite v4.11 from US Environmental Protection Agency.
Using MCI method the log Koc of the test item was calculated to be 5.8461 and Koc to be 7.016E+5 L/kg at 25 °C. Using log Kow method the log Koc of the test item was calculated to be 3.7716 and Koc to be 5910 L/kg at 25 °C. The substance is not within the applicability domain the models. Thus, the estimation may be less accurate. The log Koc of 5.8461 was regarded as worst case assumption and was therefore chosen as key value for chemical safety assessment.
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.
