Why choose dedicated automotive wheel paint?
CoreAdvantages
High Gloss·Mirror Metallic Texture
The hydroxy acrylic amino baking paint system has a gloss greater than 90GU, presenting a mirror-grade full metallic appearance. Aluminum powder directional alignment technology gives silver metallic paint excellent metallic flake effect. The clear topcoat layer gives the coating a diamond-like deep gloss and protection. The RAL full color range supports custom color matching for various wheel brands.
Salt Spray Resistance 1000h·Wheel-Specific
The coating's salt spray resistance is greater than 1000h, far exceeding the industry standard of 500h for passenger car wheel coatings. Resistant to brake dust (high-temperature alkaline) without corrosion / resistant to de-icing salt / resistant to car wash chemicals. Stone chip impact test ISO20567 rating less than grade 2 protects wheels from being damaged by road gravel.
High-Temperature Baking · Assembly Line Compatible
Adapted for 140-160°C baking for 20-30 minutes on automated wheel hub coating lines. Forms a complete coating system with wheel hub pretreatment (passivation/powder primer). Electrostatic rotary bell spraying ensures uniform film thickness (20-25 microns). Can coat 2000-4000 wheel hubs per shift.

Frequently AskedFAQ
ApplicationProcess
Surface preparation
Clean substrates thoroughly of oil and rust. Blast steel to Sa2.5. Pre-treat per product spec to keep the substrate clean. Ambient 5-40°C, relative humidity<85%。
Primer / pre-treatment
Select the matching primer or pre-treatment per substrate and system. Mix strictly at the stated ratio and control DFT. Proceed after the primer dries; pre-stripe critical areas.
Main-coat application
Apply the main coat per the process spec, strictly controlling DFT, temperature/humidity and flash-off to keep the film uniform without sagging or pinholes.
Curing process
Cure fully by stoving or by ambient air drying as the product requires. Keep oven temperature uniform within ±5°C and ramp up gradually to avoid coating defects. For ambient-curing grades, ensure adequate ventilation and suitable humidity.
Inspection & acceptance
Inspect all parameters: dry film thickness, adhesion, gloss, colour difference and chemical resistance. Full performance testing is carried out against the relevant standards. Only after everything passes are the test report and warranty issued, and the goods are packed and shipped in dust-free conditions.
