Abstract

The invention relates to a UV-curable coating composition, and more especially relates to a UV-curable coating composition that includes urethane acrylate resion, multifunctional acrylate resin and a photopolymerization initiator component with specific combinations of an absorption wavelength. Moreover, specific additives are used in mixing, so physical properties such as appearance, fluidity, attachment to multiple substrates, curing, thermal resistance and re-coating are excellent. Therefore, the UV-curable coating composition is suitable for various materials, reduces a defect rate of an evaporation process, and overcomes the disadvantages, namely, environment pollution and waste water treatment, of a wet-type coating method.

Description

technical field [0001] The present invention relates to an ultraviolet curable coating composition, and more specifically, to an ultraviolet curable coating composition comprising a urethane acrylate resin, a multifunctional acrylate, and a specific combination of A photopolymerization initiator component that absorbs wavelengths, and specific additives are used in combination to achieve excellent physical properties such as appearance, fluidity, adhesion to various substrates, curability, heat resistance, and recoatability, making it suitable for many applications. This kind of material can reduce the defect rate of the evaporation process, and can improve the shortcomings of the wet plating method, that is, the environmental pollution problem and the waste water treatment problem. Background technique [0002] Metallic surface coating of plastic materials is lighter than metal coating, and it has the same excellent appearance as metal, so it is widely used as decorative ma...
