RADIATION-CURABLE COATINGS FOR WOOD SUBSTRATES FROM MULTIFUNCTIONAL ACRYLATE OLIGOMERS

摘要

The invention detailed herein comprises a family of radiation-curate a coating formulations specifically for wood substrates. These coating formulations are based on multifunctional acrylate resins formed by the reaction of acrylate monomers and oligomers with ß-keto esters (e.g., acetoacetates), ß-diketones (e.g., 2, 4-pentanedione), ß-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other ß-dicarbonyl compounds that can participate in the Michael addition reaction. These coating resins will cure under standard UV-cure conditions without the addition of traditional photoinitiators.
