Epoxy-Polyester Hybrid

 

Hybrids offer most of the advantages of the epoxies in mechanical and chemical resistance properties and offer improved properties such as greater resistance to yellowing during cure, better transfer efficiency, and cleaner, brighter colors than many epoxy formulations. They are sometimes more economical than epoxies but do have less solvent resistance. Though they are better than epoxies, hybrids are not recommended for exterior exposure.
