Our Electronic Potting (Model HY-9055) has stable performance with customizable parameters; key specifications are as follows: it is a dual-component liquid silicone (A and B), both appearing as liquid with a dynamic viscosity of 3000±500. The mixing ratio of A and B components is 1:1 by weight, with an operating time of 30-120 minutes. Basic curing takes 3-5 hours, and full curing takes 12-24 hours. After curing, the hardness is 55±5 Shore A, with excellent adhesion. Thermal conductivity is ≥0.4 W(m·k), dielectric strength ≥25 KV/mm, dielectric constant 3.0~3.3 (1.2MHz), volume resistivity ≥1.0×10¹⁶ Ω·cm, and flame retardancy meets UL94-V1. Shelf life is 12 months, non-hazardous for general chemical transportation.
Product Features & Advantages
- Solar-Grade Thermal Conductivity: Efficiently dissipates heat generated by solar junction boxes during long-term outdoor operation, avoiding component overheating and ensuring stable power transmission.
- Fast Room-Temperature Deep Curing: Enables rapid deep curing at room temperature, improving production efficiency, suitable for mass production of solar junction boxes; curing speed is adjustable according to environmental conditions.
- Superior Outdoor Durability: Excellent UV resistance, weather aging resistance and temperature stability, adapting to outdoor extreme temperature fluctuations (-60℃ to 220℃) and harsh weather conditions.
- High Insulation & Flame Retardancy: UL94-V1 flame retardancy and high dielectric strength effectively prevent short circuits and fire risks; high volume resistivity ensures safe insulation of junction box electronics.
- Strong Adhesion & Waterproofing: Bonds well to various solar junction box materials (plastics and metals), forming an impermeable waterproof seal to prevent moisture intrusion and component damage.
- Environmentally Friendly & Compliant: Fully meets EU RoHS directives, non-toxic, non-hazardous, and environmentally friendly, complying with global solar industry environmental standards.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Thoroughly stir Component A to mix settled fillers evenly, and shake Component B thoroughly to ensure uniform viscosity; slight stratification during storage does not affect performance after stirring.
- 1:1 Weight Mixing: Strictly mix Component A and Component B at a 1:1 weight ratio, stirring continuously until homogeneous to ensure optimal curing effect.
- Vacuum Defoaming: After mixing evenly, place the mixed adhesive in a vacuum container and defoam at 0.08MPa for 3 minutes to remove air bubbles, ensuring dense, bubble-free encapsulation.
- Curing Process: Pour the defoamed adhesive into solar junction boxes, cure at room temperature. Proceed to the next process after basic curing (3-5 hours), and ensure full curing (12-24 hours) for optimal performance; environment temperature and humidity affect curing speed.
