(XDI, an aliphatic diisocyanate) reacts with water. From this reaction,
the diamine XDA is formed and CO2. The conversion of XDI to XDA in water
is fast. It has been shown, in the environmental studies, that XDA is
hydrolytically stable. Based on this information (e. g. half-life XDI
less than 12 hours; XDI is not present in the environment), it is
considered justified to conclude that the CSA for the environment needs
to based on XDA.
