Anti-soiling self-cleaning solution for painted surfaces
Feibo painted-surface self-cleaning coating uses nano photocatalytic and super-hydrophilic technology so painted building surfaces stay clean with sunlight and rain.
It sharply reduces manual cleaning cost, extends paint life and keeps buildings looking new — for a lasting, green, low-carbon urban environment.
Product overview
Painted-surface self-cleaning coating liquid
Product features:
- Nano self-cleaning technology — the coating is transparent and does not change the finish
- Super-hydrophilic surface, water contact angle below 10°: rain rinses dirt off automatically
- Effectively resists dust and organic soiling for a surface that stays clean longer
- Continuously breaks down harmful components in adhering pollutants (oil, carbon particles)
- Less manual cleaning, lower maintenance cost, longer paint life
- Easy to apply — suitable for complex curves and large areas
Functions:
Super-hydrophilic, anti-static, anti-soiling, self-cleaning, longer coating life
Typical uses:
Rail vehicles, high-speed trains, buses, cars and decorative facade paint — especially in dusty, heavily polluted, high-maintenance environments.
Main ingredients:
Titanium dioxide, tantalum oxide, zirconium oxide, nano dispersions and others
Industry pain point 1: building curtain walls (aluminium composite, glass, etc.)
Urban facades sit in dust, acid rain and exhaust: soiling builds up and is hard to clean
Drying rain leaves limescale streaks; large areas of facade “blacken and yellow”, hurting the city’s image
Cleaning at height is expensive and gondola work carries safety risks
Frequent pressure or acid washing damages the aluminium surface and shortens coating life
Typical scenarios: aluminium composite panels, dry-hung stone curtain walls, shaped facades
Industry pain point 2: rail transport (high-speed rail, metro, buses, locomotive bodies)
At speed the body attracts iron dust, exhaust oil film, dust and rain grime that is hard to remove
Short wash cycles (a high-speed train needs washing every 4,000 km) with very high labour and equipment cost
Large, complex bodies: conventional cleaning is slow and hazardous
Frequent washing damages the coating, ages the body and hurts the fleet’s image
Typical scenarios: high-speed trains/EMUs, metro, intercity rail, buses, special engineering vehicles
Professional coating protection — results you can see
After coating, rain spreads naturally across the surface and dirt does not stick: clearer glass, cleaner paint, a surface that stays looking new.
Application process
We follow a standardised nano painted-surface coating process that protects paint quality and appearance while reliably delivering long-term self-cleaning, anti-soiling and anti-static performance. Typical steps:
STEP 1
Site survey and feasibility
Our technical team surveys the target surface (train body, curtain wall, etc.), confirms feasibility, assesses the material (aluminium, stainless steel, car paint) and soiling type and prepares a dedicated application plan.
STEP 2
Sample test and pre-assessment
Before full-scale application a local sample is sprayed and verified, testing anti-soiling, anti-static and self-cleaning indicators to give the project quantified early data.
STEP 3
Specialist cleaning and surface preparation
Surfaces are cleaned with soft neutral water plus specialist detergent and tools — no dust, no dirt, no oil film.
STEP 4
Precision spray application
Once the substrate is fully dry, the nano coating is applied evenly by spray, brush or semi-automatic equipment, with film thickness controlled for an even film — no runs, no misses.
STEP 5
Ambient curing
After application the coating cures naturally for 4–6 hours into a dense, highly transparent, highly hydrophilic self-cleaning protective layer.
STEP 6
Acceptance test and confirmation
Suitable for high-speed trains, metro, buses, aluminium curtain walls, coated metal panels and urban facilities — keeping them looking good with less maintenance.
