  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(CF3S03)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.

  使用改良的双包装系统，可以在各种基材上涂覆固化的液态环氧树脂组合物，方法是先在基材上涂覆具有 Sn(CF3S03)2 式的催化剂，然后将涂覆的基材与树脂组合物接触。在这种方案中，从制备涂漆基材到基材与树脂组合物接触之间会有相当长的时间间隔。
