Abstract: This disclosure provides a plywood article that is pre-cured or cured. The plywood includes a first wood veneer, a second wood veneer disposed opposite the first wood veneer and an adhesive composition disposed between the first wood veneer and the second wood veneer. The adhesive composition is either cured or not cured. Prior to cure, the adhesive composition consists essentially of an isocyanate component and Kaolin. After cure, the cured adhesive composition consists essentially of a self-polymerization product of the isocyanate component and the Kaolin. The Kaolin is present in an amount of from greater than 10 to 50 weight percent based on a total weight of the adhesive composition. Moreover, each of the first and second wood veneers independently has a moisture content of from 0 to 45 weight percent.

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