Gelcoat

Gelcoat is a type of surface coating that is applied to the molds of composite parts to create a smooth, glossy, and durable finish. It is a specialized resin-based material that is pigmented to provide color and protection to the underlying fiberglass or composite structure. Gelcoat is typically made from polyester or epoxy resin and contains additives such as pigments, fillers, and additives for UV resistance and weatherability. It is applied in a liquid form and cures to a hard, glossy finish. Gelcoat not only enhances the aesthetic appearance of the finished part but also provides protection against UV radiation, water absorption, and chemical exposure. It is commonly used in the production of boats, automotive parts, shower stalls, and other fiberglass-reinforced components.
