Ecology coatings patents ENVIRONMENTALLY FRIENDLY COATING
Patent No. U.S. 7,323,248 B2
Ecology Coatings, Inc. has been granted a patent for an actinic radiation curable, substantially all solids composition comprising a mixture of at least one oligomer selected from a group consisting of a urethane acrylate, an aliphatic urethane acrylate, an aliphatic urethane triacrylate, a hexafunctional urethane acrylate, a siliconized urethane acrylate, an aliphatic siliconized urethane acrylate, and combinations thereof, wherein the at least one oligomer is present in the mixture between 15-40% of the composition by weight; at least one monomer selected from a group consisting of an isobomyl acrylate, a tetrahydrofurfuryl acrylate, a propoxylated glyceryl triacrylate, and combinations thereof; at least one free radical photoinitiator; at least one surfactant; and at least one inorganic nano-filler; wherein the composition has a room temperature viscosity up to approximately 500 centipoise; wherein the composition is a clear coat composition; and wherein the composition when cured as a coating on a composite material is an abrasion and scratch resistant coating having at least one property selected from the group consisting of at least 4H hardness; no yellowing after 7 weeks of accelerated ultra-violet (IJY) radiation testing; 99+% adhesion after 7 weeks of accelerated UV radiation testing; and no softening when wiped at least once with cloth soaked with methyl ethyl ketone wherein the composition is prepared using essentially no solvents.
