PERMANENT Protection from graffiti tagging

MarMacʼs PSC 3705 is a permanent, silicone coating with strong anti-graffiti properties, formulated to protect a wide variety of surface substrates from damage caused by aerosol paints and more. PSC 3705 cures in the presence of humidity and can be applied via an airless sprayer, nap roller, or brush. The final coating is highly hydrophobic, weather-resistant, and dries to a clear, visible matte finish. Vandalism from spray paint, markers, stickers, chewing gum, etc. exhibit poor adhesion on the coating and can be easily removed with a stiff bristle brush or power washer while keeping the PSC 3705 Permanent Anti-Graffiti Coating unharmed. The coating is perfect for a variety of surfaces including concrete, brick, and other cementitious surfaces, metal, and wood.

Solution of a high-molecular, curable polysiloxane in aliphatic hydrocarbons.

MarMacʼs PSC 3705 Permanent Anti-Graffiti Coating is used undiluted. The product can be applied by airless spraying as well as by brush or roll. Depending on the porosity of the surface, it may be necessary to apply a second coating.

The coating is transparent and promotes deepening of the substrate’s color and leaves a slight gloss as well.

During spraying of textile auxiliaries, and other surfaces, aerosols arise. Aerosols might cause a potential risk for humans. Therefore, spray only in closed installations which provide for good air extraction and good room ventilation. Do not inhale aerosols!
