  • Proppant
    Patent number: 9719011
    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.
    Type: Grant
    Filed: October 29, 2009
    Date of Patent: August 1, 2017
    Assignee: BASF SE
    Inventors: Christopher M. Tanguay, John Erickson, Victoria Manea, Jyh-Chiarng Huarng, Rajesh Kumar, Fikri Emrah Alemdaroglu
