Abstract: A proppant comprises a particle and a polyoxazolidone isocyanurate coating disposed about the particle. The polyoxazolidone isocyanurate coating comprises the reaction product of a glycidyl epoxy resin and an isocyanate in the presence of a catalyst. A method of forming the proppant comprises the steps of providing the particle, providing the glycidyl epoxy resin, providing the isocyanate, and providing the catalyst. The method also includes the steps of combining the glycidyl epoxy resin and the isocyanate in the presence of the catalyst to react and form the polyoxazolidone isocyanurate coating and coating the particle with the polyoxazolidone isocyanurate coating to form the proppant.

Abstract: A proppant includes a particle present in an amount of from 90 to 99.5 percent by weight and a polymeric coating disposed about the particle and present in an amount of from 0.5 to 10 percent by weight, based on the total weight of the proppant. The polymeric coating is formed from a curable composition comprising an isocyanate, an acrylate, and a polyol. A method of forming the proppant includes the steps of combining the isocyanate, the acrylate, and the polyol to form the curable composition, coating the particle with the curable composition, and curing the curable composition to form the polymeric coating.
