Patent ID: 8426485

Claim:
A low-gloss dry-erase coating formulation comprising a mixture of: an acrylate silica blend for reducing gloss by blending silica and by forming an incompatible phase during curing to produce microroughness, wherein the acrylate silica blend is present in said coating formulation in an amount between about 25 and 65 percent by weight, and wherein the acrylate silica blend comprises: (i) between about 30 and 50 weight percent dipropylene glycol diacrylate, (ii) between about 10 and 30 weight percent isodecyl acrylate, (iii) between about 30 and 50 weight percent polyester acrylate, and (iv) between about 0.1 and 20 weight percent silica; an acrylate selected from a group consisting of an aliphatic urethane acrylate and a polyester acrylate for enhancing physical properties of the mixture, wherein said acrylate is present in said coating formulation in an amount between about 5 and 35 percent by weight; and a polyfunctional reactive diluent for increasing crosslink density and the hardness, toughness, and chemical resistance of the surface coated with said mixture, when reacted with other oligomers and monomers of said mixture, wherein said polyfunctional reactive diluent is present in said coating formulation in an amount between about 20 and 50 percent by weight.
