Rooflight Sheet Resin is a high-performance unsaturated polyester resin formulated specifically for manufacturing translucent or transparent fiber-reinforced plastic (FRP) sheets. These sheets are widely used in industrial, agricultural, and commercial buildings where natural lighting and weather resistance are essential. The resin is designed to deliver excellent light transmission while maintaining structural integrity and environmental durability.
This resin is typically used with fiberglass reinforcements like chopped strand mat or woven roving and is compatible with room-temperature curing systems. Its ability to withstand UV radiation, moisture, and varying temperatures makes it ideal for long-lasting applications in roofing and cladding systems.
Rooflight Sheet Resin is generally based on Orthophthalic polyester and is formulated for use in transparent or semi-transparent FRP roofing sheets. It ensures high clarity, good mechanical strength, and reliable adhesion to fiberglass reinforcements. The resin cures at room temperature using catalysts such as MEKP, producing strong, weather-resistant sheets suitable for both flat and corrugated roof designs.
It supports high light transmission while offering excellent protection from UV degradation, yellowing, and surface wear. This makes it suitable for skylights, greenhouse panels, and daylighting systems in commercial structures.
We deliver high-quality, innovative resin solutions with a strong focus on customer satisfaction and lasting performance.
