<p>A non-sacrificial, penetrating, anti-graffiti coating consisting essentially of the combination of alkali metal silicate, such as for example potassium, lithium or sodium silicate, deionized water, ethylene-glycol colloidal silica, aminopropyl oxysilane, fluorinated polyurethane, and alkali metal methyl siliconate, such as for example potassium, lithium or sodium siliconate. The coating is a surface penetrating coating that is chemically resistant, and possesses a surface tension higher than the surface tension of the surface to which it is applied, whereby paint applied to said coating is easily removed.</p> |
