ABSTRACT:
The present invention discloses 1,3-dialkylimidazole-2-thiones catalysts for epoxy/anhydride reactions (and other reactions) and a method of making these catalysts. Epoxy/anhydride coatings containing these improved catalysts offer the following advantages: improved appearance (especially since even weeks after application the coatings still have a "wet" look); better pot-life; improved resistance to alkaline substances which will improve durability; improved solubility; and coatings which have a reduced volatile organic content (VOC).
