The Anti-Graffiti Solution for STB Trams
Chimtitan supported the refurbishment of the V3A-93-CH tram operated by Bucharest's public transport company (STB) by supplying an anti-graffiti coating system that allows easy graffiti removal without damaging the finish.
The Challenge
Graffiti on public transport vehicles is a major problem in large cities:
- High costs for cleaning and repainting
- Degraded appearance of the vehicles
- Negative impact on the image of public transport
- Aggressive cleaning methods that destroy the original coating
The Chimtitan Solution: Topcoat 351 AG
The two-component acrylic-polyurethane topcoat in the 351 AG (Anti-Graffiti) series delivers:
Permanent Protection
- A smooth, non-receptive surface that prevents spray paint from bonding
- Graffiti can be wiped off with mild cleaning agents, with no abrasion required
- More than 50 cleaning cycles with no need for recoating
Technical Performance
- Outstanding resistance to UV radiation — no fading or loss of gloss
- Resistance to weathering and extreme temperature swings (-30°C to +80°C)
- Superior long-term gloss and colour retention
- Excellent adhesion to steel, aluminium and plastics
Complete Coating System
- Surface preparation — abrasive blasting to Sa 2.5 plus degreasing
- 2K epoxy primer, 302 series — anti-corrosion protection
- Intermediate coat, 302 series — additional barrier
- Topcoat 351 AG — anti-graffiti finish in custom RAL colours
