Product type
Gelcoat resin is a type of polyester resin used primarily as a protective and decorative layer in composite materials. It is typically made from unsaturated polyester resins combined with pigments and additives to enhance its properties. When cured, gelcoat forms a hard, glossy surface that is resistant to UV light, chemicals, and moisture, making it ideal for various applications in the marine, automotive, and construction industries.
| Color options | Various colors available, including clear and opaque |
| Curing time | Typically ranges from 1 to 4 hours at room temperature |
| Viscosity | Usually between 2000 to 6000 cP |
| Density | Approximately 1.1 to 1.5 g/cm³ |
| Tensile strength | Typically around 40 to 70 MPa |
| Flexural strength | Ranges from 80 to 120 MPa |
When selecting gelcoat resin, consider the specific application and environmental conditions it will face. Buyers should specify the required color, curing time, and any necessary additives for UV resistance or flexibility. It's also important to inquire about the resin's compatibility with other materials used in the composite structure. Quantities will depend on the size of the project, so providing detailed dimensions can help suppliers offer accurate quotes.
