Polyester Resins are the most widely used resins in the composites industry. Sometimes referred to as Fiberglass Resins, Polyester Resins are less expensive, offer some corrosion resistance, and are more forgiving than epoxies. The majority of all fiberglass parts are constructed using Polyester Resins because they are easy to use, fast curing, and tolerant of temperature and catalyst extremes.
Premium polyester gel coat delivers superior cosmetics and durability for parts and molds. Choose from traditional gel coats such as white, neutral, and clear, as well as orange or black tooling gel coats. All of our gel coats resist UV degradation and water absorption.
