Anti Graffiti

Anti-Graffiti Powder Coatings:

Powder with resistance to contamination:

1. Product features
The main characteristic of the anti-graffiti powder 11X-XXX-YYYY (previous code: DS-0XXXA) is the high resistance to contamination: a special formulation makes products coated with this powder impenetrable to external pollutants, such as dirt and permanent markers/inks. While the cleaning of surfaces painted with regular powders would leave stains or blotches, surfaces painted with anti-graffiti powder will be cleaned easily with no traces of pollutants. These powders are all for sublimation and they are typically smooth and glossy.

3. Variants and special formulations
There are several variants of this series. This powder can be produced:
- Clear or colored opaque;
- Super durable, Class 2;
- Low curing;
- Antimicrobial.

4. Possible usage and applications
The Anti-graffiti series (11X-XXX-YYYY) provides a reliable solution for areas subject to the risk of dirt and contamination such as urban furniture and public spaces. In addition, this powder coating has great advantages in office environments where ink stain may soilshelves and objects. Anti-graffiti powders provide the ability to remove dirt very easily, while maintaining a clean appearance.


5. Anti-graffiti test
The anti-graffiti properties of this series of powders are tested according to the international standard UNI 11246, which defines the method and the procedures to determine the resistance to contamination. Some of the steps of the procedure are shows below:


Several staining agents have been tested, removing each one of them with a suitable cleaning product.

6. Anti-graffiti test with colored powders
The anti-graffiti proprieties are also tested soiling with several staining agents some sample panels painted with DS-0821-SA (colored powder suitable for sublimation) and with PU RAL shades. The steps of this test are: 
- Soiling of the pattern with: lipstick, marker, N50 pentel, acrylic spray; 
- Drying of the staining agents in an oven at 80°C (176°F) for 120í; 
- Conditioning, at 23°C (73.4°F), for at least 120í with relative humidity at 50%; 
- Removing of the staining agents with commercial ethylic alcohol; 
- Removing of the staining agents with a mixture etasol/MEK 70:30. Test on DS-0821-SA

7. Resistance to chemicals (Acetone)
The resistance to chemicals has been tested for this series. A 1 ml amount of commercial acetone* has been poured on the surface of a sample coated with PE411 + DS- 0810SA; after 10 seconds the solvent has been wiped with a soft cloth. The test has been simultaneously carried out on a standard white polyester. The test has shown how a standard powder-coating product lose gloss when touched by aggressive solvents like acetone, leaving a stain where the drop was, and damaging the surface of the sample. The sample coated with the antigraffiti product DS-0810SAinstead was totally unchanged, with no loss of gloss and no stains left in the area of the test, proving exceptional resistance to aggressive solvents.
