Case studies · Painted-surface self-cleaning

Train bodies and building finishes that look new after every rain

Feibo painted-surface self-cleaning coating is proven on rail vehicles, aluminium-panel curtain walls and car paint. The transparent super-hydrophilic film leaves the finish unchanged, lets rain wash off grime, cuts cleaning and extends paint life.
