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 and a hybrid coating disposed about the particle. The particle is present in an amount of from about 90 to about 99.5 percent by weight based on the total weight of the proppant and the hybrid coating is present in an amount of from about 0.5 to about 10 percent by weight based on the total weight of the proppant. The hybrid coating comprises the reaction product of an isocyanate component and an alkali metal silicate solution including water and an alkali metal silicate. A method of forming the proppant includes the steps of providing the particle, the isocyanate composition, and the alkali metal silicate solution. The method also includes the steps of combining the isocyanate composition and the alkali metal silicate solution to react and form the hybrid coating and coating the particle with the hybrid coating to form the proppant.
