High-speed train body self-cleaning coating

Train bodies pick up iron dust, oil film and rain grime at speed; after coating, dirt does not stick and wash cycles stretch out.

ProductFeibo painted-surface self-cleaning coating

Background

The problem

At speed the car body attracts iron dust, exhaust oil film, dust and rain grime; wash intervals are very short and the labour and equipment cost is high. The large, complex body is slow to clean and frequent washing wears the paint.

Scope of work

What we did

Surveyed paint type and soiling; drew up a dedicated plan
Local sample spray to verify anti-fouling, anti-static and self-cleaning targets
Cleaned the body with soft neutral water and specialist detergent — no dust, no oil film
Precision spray with controlled film thickness — no runs, no misses
Ambient cure 4–6 h, then acceptance test

Results

Results and value

The body is now super-hydrophilic and anti-static: iron dust and oil film do not bond, and rain or a simple rinse restores a clean finish. Wash intervals lengthen, O&M cost falls, the paint is protected and the fleet looks better.
