Photovoltaic Module Junction Box Potting Adhesive

Product Introduction

The product is a fluid silicone composite material made from silicone resin as the base, filled with functional fillers, and processed through a special technique. It reacts with moisture in the air at room temperature to cure into a high-performance elastomer, featuring the excellent physical and electrical properties of silicone materials.

Two-component system: 6:1/5:1 ratio

Condensation type: Fast room temperature curing, UL certified

Features: Excellent yellowing resistance, high-temperature and high-humidity resistance, superior waterproofing, good adhesion to PPo, PA,and other materials.

Excellent Thermal Conductivity and Heat Dissipation:Provides efficient heat transfer performance to help dissipate heat generated by photovoltaic junction box components and reduce the risk of overheating during continuous operation, improving the reliability of solar module electrical systems.

Reliable Electrical Insulation Performance:Offers excellent dielectric properties and electrical insulation performance, helping prevent short circuits, current leakage, and electrical failures in photovoltaic junction boxes and related components.

Low Viscosity and Excellent Flowability:Features optimized viscosity and good flow performance, allowing the potting adhesive to penetrate complex junction box structures, fully encapsulate internal components, and reduce the risk of void formation.

Excellent Moisture Resistance and Environmental Protection:Forms a durable protective layer after curing, helping prevent moisture ingress, dust contamination, and environmental corrosion while improving the service life of photovoltaic junction box components.

Superior UV and Weathering Resistance:Maintains stable physical properties under prolonged outdoor exposure, resisting UV radiation, temperature changes, humidity, and harsh environmental conditions commonly found in solar applications.

Excellent Flame Retardant Performance:Provides enhanced safety performance with flame retardant characteristics, helping meet the requirements of photovoltaic electrical protection applications.

Strong Adhesion and Long-Term Reliability:Provides reliable adhesion to common junction box materials and photovoltaic components, maintaining stable performance under thermal cycling, vibration, and long-term outdoor operation.

Good Processing Performance:Suitable for automated dispensing and potting processes, providing efficient application performance for high-volume photovoltaic module manufacturing.

When selecting a junction box potting adhesive, key factors such as thermal management requirements, electrical insulation performance, material compatibility, curing conditions, and long-term outdoor reliability should be considered.
