Abstract:
A curable resin coated proppant which resists damage due to premature curing in the summertime comprises a proppant particle substrate and a curable resin coating on the proppant particle substrate. The curable resin coating comprises a curable polymer resin, a conventional (aldehyde functional) curing agent for the curable polymer resin, an organofunctional compound comprising one or more polyols, one or more polyamines or a mixture thereof, and a non-aldehyde functional covalent crosslinking agent for the polymer resin.

Claim (Index 15):
The curable resin coated proppant of  claim 1 , wherein the amount of phenol leaching exhibited by the inventive curable resin coated proppant when subjected to the phenol leaching analytical test described in the specification is less than 100 ppm at pH=2 and at pH=7 and at pH=11.
