Abstract: A fire-resistant polyurethane composition and a fire-resistant product comprising the fire-resistant polyurethane composition. The fire-resistant polyurethane coating composition comprises: an aromatic isocyanate component, a polyol component, and an intumescent component; wherein the aromatic structure in the polyurethane backbone is ≥24wt%. The fire-resistant polyurethane composition could provide surprisingly good intumescent layer toughness as well as good insulation performance.

Abstract: Coated proppant particles are prepared from a coating composition that includes at least one polyisocyanate and an isocyanate trimerization catalyst. The coating composition preferably is devoid of an effective amount of a urethane, urea and carbodiimide catalyst. The coating composition cures rapidly at moderate temperatures, and bonds to itself well under conditions of heat and pressure as are experienced by the particles in subterranean formations.
