Abstract
A double-layer coating composition having improved sparkling effect, and a method of coating the same are provided. The composition includes a first coating, which reinforces the sparkling effect and contains a greater amount of Al particle; and a second coating, which reinforces chromaticity and contains a less amount of Al particle. The method includes applying a first coating on an article and applying a second coating thereon.
Claims11
A double-layer coating composition having an improved sparkling effect, comprising:
- a first coating that includes about 45 to 65 wt % of acrylic resin, about 15 to 30 wt % of acid epoxy resin adduct of acrylsiloxane resin, about 1 to 5 wt % of a color pigment, about 0.1 to 1 wt % of aluminum (Al) particle, about 10 to 20 wt % of at least one additive selected from a surface modifier, an ultraviolet (UV) absorber, a pinhole preventive, a reaction inhibitor, and an anti-sagging agent, and about 2 to 10 wt % of a solvent;
- and
- a second coating that includes about 45 to 65 wt % of acrylic resin, about 15 to 30 wt % of acid epoxy resin adduct of acrylsiloxane resin, about 1 to 5 wt % of the color pigment used in the first coating, about 0.01 to 0.08 wt % of Al particle, about 10 to 20 wt % of at least one additive selected from a surface modifier, a UV absorber, a pinhole preventive, a reaction inhibitor, and an anti-sagging agent, and about 2 to 10 wt % of a solvent.
A method of double-layer coating, comprising:
- applying a first coating composition, including about 45 to 65 wt % of acrylic resin, about 15 to 30 wt % of acid epoxy resin adduct of acrylsiloxane resin, about 1 to 5 wt % of a color pigment for coating, about 0.1 to 1 wt % of Al particle, about 10 to 20 wt % of at least one additive selected from a surface modifier, a UV absorber, a pinhole preventive, a reaction inhibitor, and an anti-sagging agent, and about 2 to 10 wt % of a solvent;
- and
- secondary coating by applying a second coating composition, including about 45 to 65 wt % of acrylic resin, about 15 to 30 wt % of acid epoxy resin adduct of acrylsiloxane resin, about 1 to 5 wt % of the color pigment used in the first coating, about 0.01 to 0.08 wt % of Al particle, about 10 to 20 wt % of at least one additive selected from a surface modifier, a UV absorber, a pinhole preventive, a reaction inhibitor, and an anti-sagging agent, and about 2 to 10 wt % of a solvent.
