Si-COAT® 531™ is a clear, semi-gloss, permanent (non-sacrificial) one coat anti-graffiti protective coating suitable for use over metal, concrete, brick, stone, wood, fiberglass and pre-existing coatings.

This single component, room temperature vulcanizing (RTV), moisture cure polysiloxane product provides excellent durability and long service life. As a result of its specific chemistry, Si-COAT 531 forms chemical bonds with the host surface to enhance adhesion properties without the need for abrasive blasting, priming, and extensive site preparation. Due to the hydrophobicity of the coating, graffiti can easily be removed from protected surfaces, simply using water under low-pressure -1200 psi - 83 bar (ASTM D7089 Cleanability Level One).
