Definition - What does Graffiti Resistant mean?
Graffiti resistant refers to the ability of a metallic surface coating to be able to withstand the adherence of inks or paints that are acrylic, synthetic or water-based. This resistance is possible due to the prior treatment of the metal's surface with an aliphatic-urethane powder coating that also protects against corrosion.
Corrosionpedia explains Graffiti Resistant
Aliphatic urethane powders (AUPs) are used to create metallic surfaces that are resistant to a wide range of external attack, including graffiti. In addition, AUPs produce a high degree of surface smoothness and exterior durability that make the surface easier to clean.
AUPs offer excellent flow properties, providing high surface area durability but reduced edge coverage. Aliphatic urethanes are therefore infused in premium durability powders and paint-resistant products.
