Resins / Gelcoats / Pigments

Thermoset resins are the main matrix material for polymer composites due to their excellent mechanical properties, thermal stability and chemical resistance. Unlike thermoplastics, which can be melted and remolded without losing their chemical properties, thermoset resins complete their irreversible chemical reactions by forming a network of cross-links during curing. Gelcoats, on the outermost layer of the matrix resin, act as a thin shell to protect the part from UV rays, moisture and outdoor conditions, giving the surface an eye-catching, shiny appearance. Pigments act as colorants for gelcoats and resins.
