Polyester Resin - Fiberglass Warehouse

To make a durable composite laminate you need to have both a reinforcement (fiberglass cloth, fiberglass mat, carbon fiber, aramid, etc.) and a resin.  Resin holds the reinforcement together and helps it conform to the wanted shape.  Resin fills the fiberglass weave. Just like there are several reinforcement options there are also a few resin options. The most commonly used resin is polyester.  It is more economical than vinyl ester and epoxy. It is the easiest of the three to use. It has a quick cure and adds dimensional stability.  It is often used in building/repairing boats, car bodies, patio decks, sporting goods, surfboards, kayaks, decorative surfaces, outdoor ponds, bath tubs, aircraft, plus more. There are several grades of polyester resins. The most popular is the Ortho General Purpose Laminating Resin (GP Resin).  It is used for general fiberglass applications.

General Purpose - This polyester resin will hold the fiberglass cloth and composite fabrics in place during boat building and layups. For multiple repairs like a bathtub, automotive fiberglass and surfboards among other projects. Fast Wet Out - For fiberglass and other reinforcement fabrics. Create composites and FRP parts for cars, motorcycles, yachts, boats, etc. Perfect for spray or apply by hand on fiberglass, wood and metal.
