Gelcoats cure through a chemical reaction known as crosslinking, usually initiated by a catalyst (such as MEKP—methyl ethyl ketone peroxide). When applied, the gelcoat forms a solid, durable surface that hardens after a specified period, typically under heat or at room temperature.

From boats to cars and architectural designs, gelcoats offer both protection and aesthetic enhancement, making them an essential material in the composite industry. Their durability, ease of maintenance, and attractive finish ensure their widespread use in a variety of applications.

• Marine Industry: Gelcoats are commonly used as the exterior finish for fiberglass boats, yachts, and other watercraft. The protective layer helps resist water penetration, corrosion, and the harsh effects of saltwater exposure.
• Automotive: Gelcoats are used in the production of composite parts for cars, trucks, and RVs, providing a high-gloss finish and additional protection against environmental factors.
• Construction: Gelcoats are used in the fabrication of composite panels, architectural elements, and other products that require a smooth, durable surface.
• Recreational Products: From sports equipment to furniture, gelcoats are used to provide a glossy, protective finish for products exposed to wear and the elements.
