Resin & Resin Hardener
Polyester, Vinylester and Epoxy Resins
Boat resin and fiberglass cloth are the main components of fiberglass hulls and decks. Resins are part of two-component systems that require resin hardener (aka catalyst) to harden and are commonly used with reinforcing materials like fiberglass. Polyester resin is relatively strong, inexpensive and easy to work with. Vinyl-ester resin is a stronger than polyester and offers greater moisture resistance. Epoxy resin is the strongest of the three, has the greatest moisture resistance and is used in the highest quality boats and in aircraft.
