Q1 : What is the difference between Polyester Resin and Epoxy Resin? Polyester resin, although it has adhesive qualities, does not bond as well as epoxy resin. Polyester resin is made to be a laminating resin, usually for fibreglass or in molds. Unlike epoxy resins, polyester resins require a catalyst instead of a hardener - they have a low shelf life because they gel on their own. Polyester resin sets much faster and is less expensive than epoxy resins, but epoxy resins are more durable, more waterproof, better bonding agents, and will last much longer, so they are better for coating artwork.
