Zusammenfassung:Solvent-based processes for producing latent curing catalysts without causing an extreme exotherm. The process of the present invention includes combining an amine compound curing agent with a solvent, heating the mixture, adding an epoxy/solvent mixture via slow addition, removing the solvent and then heating the remaining composition. Following the heating, a phenolic resin is added to produce the final catalyst. The final catalyst comprises an amine compound, an epoxy, phenolic resin and a solvent. Catalysts having differing properties may be produced by varying the elements of the catalyst.
