Test of stain removal from anti-graffiti special powders

A test was made at Decoral^® Lab in order to check how easy it is to remove stains from the special series of anti-graffiti Powders 11X-XXX-YYYY (former code DS-0XXXA). Stains were made with various materials on a metal sample coated with anti-graffiti Powder; then such materials have been removed wth various cleaning products.

Picture 1 shows the stained sample; picture 2 shows the sample after it has been cleaned with various products.

If the right cleaning product is used, every single trace of stains can be removed, even if the stains had been made with very aggressive materials, such as black permanent markers and spray paints. The white, glossy surface of the sample is now clean again. *mix 70:30 of etasol:methylethylketone

If we compare these results with the results of the same test made on standard Powders (Picture 3), we realize that the features of this specific anti-graffiti Powders make it very easy to remove the stains.
