Global electric passenger bus output surges in 2026. Lightweight aluminum alloy frames are widely adopted to reduce vehicle weight, but aluminum and steel fasteners produce galvanic corrosion under road salt and humid climate. Ordinary solvent paint cannot form stable insulating barrier, leading to frame perforation within 3 years. FLDC independently develops full waterborne insulating coating dedicated to new energy bus aluminum structures.
Complete matching coating system:

1. Waterborne special aluminum adhesion primer (insulating transition layer)
2. Waterborne high-resistance intermediate coating isolate metal potential difference
3. Waterborne aliphatic polyurethane insulating topcoat
   Core Advantages:
   ✅ High dielectric insulation block aluminum-steel galvanic corrosion effectively
   ✅ Ultra-low VOC, meet EU vehicle environmental emission standards
   ✅ Resist road salt, rainwater and high-temperature engine environment
   ✅ Flexible film adapt vehicle vibration without cracking
   ✅ Fast-drying assembly line formula shorten bus production cycle
