Powder Coating for Shared Bike Wheel Hubs
1. Substrate Compatibility
Designed for steel and aluminum wheel hubs. After phosphating or passivation pretreatment, the coating forms a firm bond with metal substrates, preventing paint peeling caused by long-term vibration during cycling.
2. Mechanical Properties for Heavy-Duty Use
Excellent impact resistance: Resist chipping from flying gravel and road bumps, suitable for high-frequency short-distance riding of shared bikes.
High hardness & abrasion resistance: Withstand continuous friction from brake dust and sediment to avoid scratches and substrate exposure.
Superior flexibility: No cracking or peeling under minor hub deformation and temperature alternation.
3. Outdoor Weather & Corrosion Resistance (Core Advantage for Outdoor Parking)
UV resistance: No yellowing, chalking or gloss loss under long-term sunlight exposure, maintaining intact appearance for 3–5 years.
Water & salt spray resistance: Guard against rainwater, acid rain and road deicing salt to prevent rust and spot corrosion on wheel hubs.
Wide temperature tolerance: No blistering or peeling under repeated high and low temperature cycles all year round.
4. Surface Practical Performance
Dense compact coating with low porosity; brake dust and oil stains can be easily washed off with clean water.
Complete gloss options: matte, semi-gloss, high-gloss; customizable colors including black, grey and engineering shades with uniform color without color difference.
Good edge coverage: Uniform powder deposition on spokes and sharp corners without thin coating or missing spray.
5. Environmental Protection & Construction Advantages
Zero solvent, low VOC, complying with environmental standards for municipal outdoor coatings with no pungent odor.
High powder recycling rate, stable mass assembly line spraying and fast curing to cut production costs for bicycle manufacturers.
Free of sagging and pinholes after curing, delivering neat finished hubs for mass production of shared bicycles. Various colors and effects can be customized according to customer requirements!
