Epoxy gelcoat 11.4kg set Sika Biresin GC155 black, heat-resistant, for molds and lamination

View by manufacturing method

First, the epoxy resin and hardener are thoroughly mixed in the required proportions, usually taking into account the temperature regime, as polymerization reactions occur at specific temperatures. Additional components, such as UV stabilizers, anti-corrosion agents, or chemical fillers (such as aluminum powder), which increase the coating's resistance to external influences, may be added to the mixture. Once a homogeneous mixture is obtained, the epoxy gelcoat is prepared for application. This process may include vacuum treatment to remove any air bubbles that may arise during the mixing process.

Chemical composition

Epoxy resin (main component), hardener (polyamide or amine hardener), pigments (for color), fillers (silicate or silicon), UV stabilizers and anti-corrosion additives.

Type by purpose

Widely used in the production and repair of ships, boats, yachts, and other watercraft, it protects fiberglass and carbon fiber structures from water, UV radiation, mechanical damage, and chemicals. Gelcoat not only protects but also imparts a glossy, smooth surface to watercraft. In the automotive industry, epoxy gelcoat is used to create glossy coatings on parts such as car bodies, aerodynamic kits, sports cars, motorcycles, and other vehicles. It helps improve the appearance and extend the service life of weather- and chemical-resistant parts. Epoxy gelcoat is used to coat various structures, such as swimming pools, chemical storage tanks, bridges, and other engineering structures. It is used to protect concrete and metal surfaces from corrosion and other external factors, as well as to create decorative coatings. It is also used to coat sports equipment such as skis, snowboards, kayaks, surfboards, and other gear. This increases their durability and improves their appearance.
