Abstract:
1. A low-gloss anti-graffiti coating formulation comprising a mixture of: between about 40 and 80 percent by weight of an acrylate silica blend for reducing gloss by blending silica and by forming an incompatible phase during curing to produce microroughness; between about 1 and 20 percent by weight of an acrylate selected from the group consisting of an aliphatic urethane acrylate and a polyester acrylate; between about 5 and 35 percent by weight of an erythritol polyacrylate diluent for increasing crosslink density, hardness, toughness, and chemical resistance of a surface coated with said mixture; and between about 0.1 and 10 percent by weight of a cross-linkable silicone acrylate to enhance the anti-graffiti property of said mixture.
