Results and discussion

Results:
not corrosive to metal

Any other information on results incl. tables

Classification according to CLP (Regulation on Classification, Labelling and Packaging of Substances and Mixtures, EC Regulation No 1272/2008, Annex 1):

The molecule does not have any acidic or basic functional groups nor does it contain halogen. The tendency of the ester and isocyanate groups to form complexes with metal is low. Performing Test C.1 according to the ‘UN Manual of Tests and Criteria’ is not possible because the substance

tends to polymerize under the test conditions (elevated temperature). Further, the isocyanate function would hydrolyze (R-NCO + H2O R-NH2 + CO2) in contact with moisture in the open system as required by the test procedure.

Therefore, an assessment of corrosive properties has to be based on an expert statement. From the chemical properties as discussed above, it is to be concluded that ‘2-Isocyanatoethyl methacrylate’ is not corrosive to metal.
