Description of key information

Modified Small Vinyl Ester is a slightly water soluble, highly viscous prepolymer. When exposed to light, Modified Small Vinyl Ester will polymerise and bind all Modified Small Vinyl Ester and most of the reactive diluent covalently in an extremely stable and highly water insoluble polymer with very low bioavailability in sediment. It is unlikely that Modified Small Vinyl Ester will reach sediment making direct and indirect exposure of sediment unlikely. See the CSA for further details.

Key value for chemical safety assessment

Additional information

Sediment simulation testing is waived in accordance with REACH Annex IX, section 9.2.1.4, column 2. Modified Small Vinyl Ester is a slightly water soluble, highly viscous prepolymer that is placed on the market as an approximately 50% solution in a reactive diluent for industrial use only. When exposed to light, Modified Small Vinyl Ester will polymerise and bind all Modified Small Vinyl Ester and most of the reactive diluent covalently in an extremely stable and highly water insoluble polymer with very low bioavailability in sediment. Modified Small Vinyl Ester is unlikely to reach sediment, thus direct and indirect exposure of sediment is unlikely. See the CSA for further details.
