Abstract:

The invention detailed herein comprises a family of radiation-curable coating formulations specifically for metal substrates. These coating formulations are based on multifunctional acrylate resins formed by the reaction of acrylate monomers and oligomers with ÿ-keto esters (e. g. , acetoacetates), ÿ-diketones (e. g. , 2, 4-pentanedione), ÿ-keto amides (e. g. , acetoacetanilide, acetoacetamide), and/or other ÿ-dicarbonyl compounds that can participate in the Michael addition reaction. An essential novelty of these coating resins is that they will cure under standard UV-cure conditions without the addition of traditional photoinitiators. Other materials, both reactive (conventional acrylates) and non-reactive (e. g. , solvents) may also be incorporated into the resin oligomers to enhance the coatings properties on metal substrates. These materials include a variety of acrylic monomers and oligomers, primary, secondary and tertiary amines, acid-functional monomers and oligomers, silicones, waxes and elastomers, among others.

Abstract:

The invention detailed herein comprises a family of radiation-curable 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 β-keto esters (e.g., acetoacetates), β-diketones (e.g., 2,4-pentanedione), β-keto amides (e.g., acetoacetanilide, acetoacetamide), and/or other β-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 photo initiators.
