UV Photovoltaic Adhesive Resin

UV (ultraviolet curing) photovoltaic adhesive resin is a core material in the solar module manufacturing industry, specifically designed to meet the demands of high-efficiency production, long-term reliability, and environmental sustainability. Utilizing UV rapid curing technology, it enables instant bonding and encapsulation while offering high transparency, superior weather resistance, and exceptional adhesion strength. This enhances the power generation efficiency and lifespan of photovoltaic (PV) modules. Below is an overview of our specialized resin solutions for PV applications:

1. Basic Functional Resin Series

• UV Photovoltaic Adhesive Resin: A general-purpose adhesive base material suitable for PV cell encapsulation and backsheet bonding, providing balanced adhesion strength and curing efficiency.

• Photovoltaic Resin: Specially designed for solar modules, compatible with EVA films, glass, and metal frames to ensure stable and reliable interface bonding.

• UV High-Adhesion Resin: Ultra-high bonding strength (>10MPa), ideal for complex load-bearing applications such as frame sealing and junction box fixation, preventing delamination and moisture ingress.

2. High-Performance Specialty Resin Series

• UV High-Transparency Resin: With over 92% light transmittance, it achieves optical performance comparable to glass, minimizing light energy loss and improving module power output.

• UV High-Weatherability Resin: Successfully passes 3,000-hour QUV aging tests, offering resistance to UV exposure, extreme temperatures (-40°C to 120°C), and humidity, making it suitable for harsh environments like deserts and coastal areas.

• UV Fast-Curing Resin: Cures within 5-10 seconds, seamlessly integrating with automated production lines, significantly enhancing module assembly efficiency while reducing energy consumption.
