Abstract: A proppant comprises a particle and a polycarbodiimide coating disposed on the particle. The polycarbodiimide coating comprises the reaction product of a polymeric isocyanate and a monomeric isocyanate, in the presence of a catalyst. A method of forming the proppant comprises the steps of providing the particle, providing the polymeric isocyanate, providing the monomeric isocyanate, providing the catalyst, reacting the polymeric isocyanate and the monomeric isocyanate in the presence of the catalyst to form the polycarbodiimide coating, and coating the particle with the polycarbodiimide coating.

Abstract: Un agente de sostén comprende una partícula y un recubrimiento de policarbodiimida dispuesto sobre a partícula. El recubrimiento de policarbodiimida comprende el producto de reacción de a isocianato polimérico y a isocianato monomérico, en presencia de un catalizador. Un método para formar el agente de sostén comprende los pasos de proveer la partícula, proveer el isocianato polimérico, proveer el isocianato monomérico, proveer el catalizador, la reacción del isocianato polimérico y el isocianato monomérico en presencia del catalizador para formar el recubrimiento de policarbodiimida, y recubrir la partícula con el recubrimiento de policarbodiimida.
