A gel coat having metal texture is composed of, by weight parts, 100 parts of matrix resin, 2-3 parts of thixotropic agent, 0.1-0.5 part of dispersing agent, 0.3-1.5 parts of surface auxiliary agent, 0.2-0.6 part of thixotropic synergist, 10-20 parts of packing, 1-5 parts of color paste, 10-20 parts of aluminum paste, 1-10 parts of pearl powder, 0.2-1 part of cellulose acetate butyrate solution with a concentration of 20%, 0.2-1 part of accelerator, 20-30 parts of styrene and 1-5 parts of acetone. The manufactured gel coat having metal texture has the advantages that (1) the gel coat can have the metal texture based on various colors, so that the product has a certain metallic luster, and the appearance effect shown by the unsaturated resin product is expanded; (2) through synergistic effects of light reflection and refraction by the aluminum paste and the pearl powder, the surface of the product maximumly reflects light entering the surface of the product, and thus the surface of the product has good glossiness; (3) a gel coat mixture is ground to a certain fineness through a sand mill, so that the surface of the product looks finer and smoother, and the metal effect is also better.
