A method for coating a UV-resistant bright and transparent composite coating
ActiveCN104226567BHigh hardnessBeautiful appearancePretreated surfacesSpecial surfacesUltravioletMaterials science
The invention provides a method for coating an ultraviolet-resistant bright and transparent composite coating. The primer varnish used in the invention is acrylic varnish, and the finishing varnish is one of trifluorofluorocarbon varnish or tetrafluorocarbon varnish. The composite coating is used on metal, carbon fiber composite materials or glass fiber composite materials to form a bright and transparent coating that can show the color of the metal body and the fabric texture of the composite material, and the composite coating film has high hardness, beautiful appearance, and Excellent weather resistance against heat and humidity, mold and UV rays.
