摘要： Phenolic resin binder systems for sand molds, used in metal casting, which improve the quality of thermally reclaimed sand, are described. The substantial or complete elimination of calcium compounds (e.g., calcium stearate and calcium hydroxide, conventionally employed as a mold lubricant and a resin curing catalyst, respectively) allows the thermally reclaimed sand to be reused over multiple thermal reclamation cycles without the adverse effects previously encountered.

摘要： A phenol-formaldehyde novolac resin having a low concentration of free phenol prepared by distilling residual phenol from a molten novolac resin and replacing at least a portion of the phenol with a solvent having a volatility equal to or less than phenol. Such modified novolac resins are suitable for the production of resin coated molding sands for shell molding and sand cores, as well as for the production of resin coated proppants for use in oil and gas recovery operations.
