  • UV-curable compositions
    Patent number: 6906136
    Abstract: A UV-curable composition is disclosed. The composition comprises a crosslinking agent, a hydroxyalkyl acrylate or methacrylate, and an acrylic polyol. The crosslinking agent is selected from the group consisting of multifunctional isocyanates, melamines, and silanes. The acrylic polyol comprises recurring units of an allylic alcohol. The composition can be irradiated to be solidified and then fully cured by the urethane, melamine, or silane reactions. Alternatively, the composition can be cured by the urethane, melamine, or silane reactions, and then fully cured by radiation. The invention provides low VOC but high performance coatings. More importantly, the invention provides a UV-curable system without the need for acrylated oligomers.
