Description of key information
In accordance with column 2 of REACH Annex VII, the test cannot be performed, as the substance decomposes in water. The half-time (t1/2) is 6.1h at ambient conditions (23°C).
Although being a more theoretical approach, an ideal structure the "corresponding diamine of the HDI Uretdione (n=2)" was considered in order to get an estimation on the behaviour of the hydrolysed product.
The calculated log Pow on the basis of the structural formula of the ideal HDI Uretdione (1,3-Diazetidine-2,4-dione, 1,3-bis(6-isocyanatohexyl) is 6.62.
The calculated log Pow of the corresponding diamine of the main constituent is 3.77.
