ABSTRACT:
Various substrates can be coated with cured liquid epoxy resin compositions using a modified two-package system by first painting the substrates with a catalyst having the formula Sn(CF.sub.3 SO.sub.3).sub.2 and then contacting the painted substrates with the resin composition. In this scheme considerable time can elapse between preparation of the painted substrates and their contacting of the resin composition.
