  A solvent system contains methoxy acetone, water and, optionally, an oxygen-containing solvent other than methoxy acetone, such as a propylene glycol monoether or diether. The solvent system is a useful solvent for a curing agent for an epoxy resin, a curing catalyst and/or a cure inhibitor. A solution of the curing agent, the curing catalyst and/or the cure inhibitor in the solvent system can be mixed with an epoxy resin, optionally dissolved in a solvent, for producing a one-component epoxy resin composition.
