Abstract
The invention relates to the modification of a curable phenolic resin system by the incorporation of alkylphenol, alkoxyphenol, arylphenol or aryloxyphenol. The resulting resin has reduced water soluble leachates which, in turn, improves the break time when the resin is used to coat proppants for treating subterranean formations.
