Vetro Power Nano-Dynamis Anti-Graffiti Coating
Permanent Anti-Graffiti Coating
Clear, ready-to-use polysilazane anti-graffiti coating that forms a permanent barrier on smooth, non-absorbent surfaces such as painted metal, aluminium and GRP.
Benefits
- Permanent, clear anti-graffiti coating
- Protects smooth, non-absorbent surfaces against graffiti and dirt
- Graffiti can be cleaned off repeatedly without reapplying
- Bonds chemically with the substrate for excellent adhesion
- Outstanding weather, UV and chemical resistance
- Cures at room temperature with atmospheric humidity
- Apply by microfibre applicator, roller or HVLP spray
- Economical and easy to apply
- Fluorine-free
Performance & Testing
- Spray-paint test: a test panel was half coated with Vetro Power Nano-Dynamis Anti-Graffiti Coating and then sprayed with blue spray paint. On the uncoated half the paint formed a solid layer. On the coated half it did not form a film and pulled back into beads.
- Dry to the touch in about 1 hour.
- Water resistant after 8 to 12 hours at room temperature.
- Fully effective after 5 to 7 days of curing at room temperature.
- Can be cleaned repeatedly without reapplying.

Vetro Power Nano-Dynamis Anti-Graffiti Coating is a clear, ready-to-use anti-graffiti coating for smooth, non-absorbent surfaces. Based on patented polysilazane technology, it forms a permanent barrier layer that bonds chemically with the substrate and cures at room temperature with atmospheric humidity. Graffiti and dirt can then be cleaned off the protected surface again and again without reapplying the coating.
It is particularly suitable for one- and two-component polyurethane and epoxy paints, polyester paints, GRP (fibreglass) and aluminium. Its main use is on the exterior of commuter and intercity trains, trams and metro trains, and it also protects other painted metal and aluminium surfaces exposed to graffiti.
Open or Close What surfaces can this anti-graffiti coating be used on?
Smooth, non-absorbent surfaces: one- and two-component polyurethane or epoxy paints, polyester paints, GRP (fibreglass) and aluminium. Its main use is on the exterior of commuter and intercity trains, trams and metro trains. For absorbent surfaces such as bare concrete, brick or natural stone, contact us before use.
Open or Close How long does the coating last?
It is a permanent coating. Graffiti can be cleaned off the protected surface repeatedly without reapplying the product. How long it performs depends on the surface, exposure and how it is cleaned.
Open or Close Is the coating transparent?
Yes. It is a clear coating, and the liquid itself is colourless.
Open or Close What is the coverage?
On average 5 to 15 ml per m² (approx. 700 to 2,150 sq ft per litre). This should not be significantly exceeded.
Open or Close What tools are used to apply it?
It is supplied ready-to-use. Depending on the substrate, apply it with microfibre applicators or paint rollers (microfibre flocking). It is also suitable for spray application: HVLP compressed air, e.g. SATA minijet HVLP, working pressure approx. 2 to 3 bar, nozzles 0.8 to 1.3 mm. The spray gun can be cleaned with n-butyl acetate.
Open or Close How should the surface be prepared?
The surface must be clean, grease-free and completely dry. Dry hard-to-reach areas such as cavities and drainage channels with absorbent cloths or compressed air. On a damp surface the coating reacts too early and cannot form a permanent seal. Substrate temperature must be between 5 °C and 30 °C, with relative humidity of 30 to 80 %.
Open or Close What are the application conditions and curing times?
Apply at an ambient temperature of at least 5 °C and 30 to 80 % relative humidity, in dry conditions, out of direct sunlight and never in rain. Mistakes can be corrected within about 10 minutes. It is dry to the touch after about 1 hour and water resistant after 8 to 12 hours at room temperature (2 hours at 80 °C, 1 hour at 130 to 180 °C). It is fully effective after 5 to 7 days at room temperature. On aluminium, steel and stainless steel, curing above 80 °C is recommended for optimum adhesion.
Open or Close Who should apply it, and what safety precautions apply?
It should be applied by trained personnel only. Test on a small area first. It is a flammable liquid: keep it away from heat and open flames, work in a well-ventilated area, wear protective gloves and eye protection, and follow the MSDS.
Open or Close Can I paint over the coating?
No. About 10 minutes after application, its repellent effect makes it impossible to apply another coat over it.
Open or Close Is it suitable for outdoor use?
Yes. It has outstanding weather, UV and chemical resistance, and its main use is on the exterior of trains, trams and metro trains.
Open or Close Do I need to reapply the coating after removing graffiti?
No. The protected surface can be cleaned repeatedly without reapplying the product.
Open or Close How do I remove graffiti from a coated surface?
Remove graffiti as soon as possible. Use a graffiti remover or a cleaner in the pH range 3 to 12. Neutral cleaners are usually enough for routine cleaning. Avoid strong mineral acids and alkalis.
Open or Close What is a permanent (non-sacrificial) anti-graffiti coating?
A sacrificial coating is removed along with the graffiti and must be reapplied after each cleaning. Vetro Power Nano-Dynamis is permanent: it stays bonded to the surface, so graffiti can be cleaned off again and again.
Open or Close What is the shelf life?
12 months from the delivery date, stored at 20 °C.
