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. 2.

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 application 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 soil shelves 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: Soiling Drying of the staining agents Cleaning
Several staining agents have been tested, removing each one of them with a suitable cleaning product.
