The surface of GRP is covered with a layer of special gel coat or coating. This design can increase the performance of GRP products, such as waterproof, corrosion resistance, chemical resistance, and aesthetics.
Structure Diagram
- Gelcoat Layer: Gelcoat is a protective surface coating that provides a smooth, shiny finish to GRP surfaces, making them more aesthetically pleasing.
- Fiberglass Reinforcement Layer：resin + fiberglass. This is a mixture of fiberglass and resin, and the commonly used types of fiberglass are fiberglass felt and fiberglass cloth.
- Non-woven Fabric Layer: Non-woven fabric serves as a connecting layer, and GRP and other materials can be tightly bonded by spraying glue.

Properties of Gelcoat GRP Sheets
- Water Resistance: Gelcoat can be used to increase the water resistance of GRP, making it suitable for applications that require water or moisture resistance.
- Corrosion Resistance: Gelcoat coating can improve the corrosion resistance of GRP, so that it has a longer service life in the environment subject to chemical corrosion.
- Aesthetics: Gelcoats can improve the appearance of GRP and are available in a variety of color and surface texture options for decorative or aesthetic needs.
- Abrasion Resistance: Gelcoat can increase the abrasion resistance of GRP and prolong its service life.
Surface Treatment
In addition to the most common glossy and matte surface treatments, the GRP surface can be processed into various texture patterns, etc.
Application of Gelcoat GRP Sheets
Flat gelcoat GRP is usually used as the skin material of composite panels, such as building wall panels, RV bodies, box truck bodies, furniture panels, etc.
