Abstract
A polymeric material may be prepared by reacting a mixture comprising an amino functional polyorganosiloxane, polyisocyanate, and polyol. The polyol may comprise a hydroxy-functional poly(meth)acrylate. The polymeric material may be used as a coating for a substrate and may inhibit fouling on a surface exposed to aquatic conditions.
