Anti-graffiti coatings
What it is
Urban surfaces (facades, urban furniture, trains, buses, tunnels) receive anti-graffiti coatings — formulations that prevent permanent adhesion of spray paints. Aliphatic PU systems create a surface so low-energy that graffiti can be removed with simple cleaning.
The PU technology applied here is typically aliphatic pu with low-energy surface, selected for the combination of mechanical, chemical and processing properties suitable for the application. Specific formulations vary by equipment manufacturer or final integrator, but the base system has stable characteristics documented in technical literature and segment-specific standards.
Why it matters
For paint manufacturers, specialized applicators and project specifiers, anti-graffiti coatings is a decision balancing technical performance, application cost and regulatory compliance. Regulatory pressure on VOC (Volatile Organic Compounds) in developed markets forced transition to waterborne systems in many applications, and Brazil follows this regulatory trajectory.
Current drivers. Sustainability in construction and industry (LEED, AQUA, EDGE certifications) values low-VOC products with documented durability. Premiumization in architectural and automotive finishes drives superior performance systems. Export of Brazilian products (furniture, structural steel, sandwich panels) requires compliance with target market standards (CARB in US, EN in EU). Modern PU formulations meet these combined requirements better than legacy alternatives.
