Polyester or unsaturated polyester resins (UPR) and vinyl ester resins (VER) combined with fiberglass reinforcements, have long been the core components of composite products. Composites One offers a wide selection of resins for composites manufacturing including advanced resins such as epoxy, acrylic, polyurethane, phenolic, and more.

Resin is the binding matrix that holds reinforcement fibers together, providing structural integrity to the final composite product. Resin transfers stress between the fibers, protects the fibrous structure from environmental and mechanical damage, and imparts desired physical and chemical properties to the composite material.
