Problems solved by technology
The solvents in the color paint layer system are ketone solvents and ester solvents with strong solubility, and the content is relatively high, about 85%-95%. In addition, the content of resin involved in the orientation of aluminum powder is very low, which cannot Ping in process of redirecting
Therefore, more stringent requirements are required for the intermediate coatings matched with the electroplated silver paint layer, which greatly increases the difficulty of the development of intermediate coatings

Abstract
The invention provides a multi-layer coating system which comprises a first coating composition, a second coating composition and a third coating composition. The first coating composition comprises polyester resin and amino resin. The second coating composition comprises modified nitro acrylic resin and electrosilvering aluminum powder. The third coating composition comprises acrylic resin and sagging-proof resin. The invention further provides a method for coating a substrate with the multi-layer coating system, and the substrate coated with the multi-layer coating system.
Description
technical field [0001] The present invention relates to a three-coat-one-bake multilayer coating system, its coating method and a substrate coated therewith, in particular to a three-coat-one-bake multilayer coating system containing an electroplated silver coating, its coating method and The substrate it is coated with. Background technique [0002] The three-coat-one-bake (3C1B) process to apply multi-layer coatings to automobile bodies or parts is a construction method often used in industrial paint construction in order to save energy and improve production efficiency. The method involves spraying a first coat, flashing off at room temperature only, a second coat, flashing off at room temperature, and finally a third coat, all three coats applied wet-on-wet, Each coat of paint dries without crosslinking and curing. The method can shorten the technological process, reduce the off-line time of the finished product, improve the production efficiency, reduce the use of ene...
