The company developed a high-temperature primer for Metro wheels and its preparation method. The high-temperature primer for Metro wheels is composed of epoxy modified silicone resin as bonding base material, anti-corrosion pigments and fillers, aluminum silver paste, additives, solvent A as paint components, low molecular weight modified polyamide resin, cashew nut oil phenol modified aromatic amine resin, 4-6 (Dimethylaminomethyl) triphenol, adhesion promoter (silane coupling agent), solvent B as curing agent components, and an appropriate amount of diluent during construction. The main purpose of the invention is to develop a high-temperature coating product for Metro wheels with high-efficiency corrosion prevention, excellent salt spray resistance, rapid drying, strong adhesion, good physical and mechanical properties, easy construction, good chemical resistance, high temperature resistance and other comprehensive properties.
