Novel Metal-free Catalysts for Epoxy Carboxy Coatings

speed in night,hongkong,china
A new class of metal-free catalysts has been developed that promotes the crosslinking reaction of epoxy functional polymers with carboxyl functional compounds and polymers. Particularly effective at much lower cure temperatures, these catalysts provide stable single package formulations and improved resistance properties. In addition, unlike amine-based compounds, these catalysts do not yellow during cure or on over-bake.
