Composite laminates are a combination of fiber reinforcement and resin. Once cured, these finished parts are primarily fiber dominant, meaning their physical properties most resemble those of the reinforcement used. So what role does resin play? It serves two basic purposes:

  • Resin holds reinforcement together and helps it conform to a desired shape.
  • Resin also helps to transfer mechanical loads from the fibers of reinforcement to the entire composite part.

At, you'll find a selection of resins and gel coat, including epoxy, polyester, and vinyl ester. These resins and gel coats are all First Quality Guaranteed so you can work with confidence.

Resin selection is based on fabric compatibility, service conditions, and the desired characteristics of the finished part. Moldmaking, molding and laminating operations can be performed with any system.

Epoxy is the higher performance and higher priced system. It is used in weight critical, high strength, and dimensionally accurate applications. Vinyl Ester resin offers corrosion resistance, heat resistance and is blended for toughness. Polyester resins are less expensive, offer some corrosion resistance, and are more forgiving than epoxies. Gel Coat is a polyester based resin made for high quality, surface finish applications.
