    Abstract: The invention features a coating composition that comprises a non-urethane acrylate or methacrylate compound in combination with a fluorochemical. Typically, the non-urethane (meth)acrylate is an aliphatic or aromatic (meth)acrylate compound and the fluorochemical typically comprises a monofunctional (per)fluoropolyether (meth)acrylate compound. The coating compositions can provide a protective topcoat layer to a variety of substrates, including wood and vinyl.
