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.

Orca 301 is a superior grade isophthalic laminating resin. This resin is used in the same applications as ortho resin but where improved physical properties are desired (ie better bonding, more impermeability to moisture, better tensile strength etc.). It cures with a surface tack for better bonding between layers. Because of the surface tack there is no need for sanding between layers.
