Additional information

The Koc value of Modified Small Vinyl Ester is calculated to 14,600 (log Koc is 4.16) at 35 °C based on the experimental data for the two main constituents of Modified Small Vinyl Ester (bisGMA, ca. 57% and its monomaleic adduct, ca. 14.5%). The high values indicate that Modified Small Vinyl Ester will bind tightly to soils and sediments and thus, reduce overall exposure potential. Monomaleic adduct of bisGMA is an organic acid that is fully ionised at neutral pH. It has a low Koc value (18) at this pH and may not bind tightly to soils and sediment. However, Modified Small Vinyl Ester is a highly, viscous liquid that is marketed as an approximately 50% solution in a reactive diluent. Modified Small Vinyl Ester will polymerise to an insoluble polymer and become immobilised in the environment.
