Product Overview
Our Electronic Potting Compound, also called Silicone Potting Compound or Electronic Encapsulation Adhesive, is a high-performance flame-retardant solution engineered specifically for electric vehicle chargers. As an experienced RTV 2 Silicone Rubber manufacturer, we focus on industrial-grade silicone materials for new energy equipment. This liquid silicone is superior to ordinary Potting Compound, with outstanding flame-retardant and insulation properties, effectively protecting EV charger electronics from overheating, short circuits and environmental damage. Technical Specifications
This two-component Addition curing silicone adopts a 1:1 weight mixing ratio of Part A and Part B, both presenting as liquid. It has a viscosity of 2500±500 Pa.s, a hardness of 45±5 A°, and an operation time of 30-60 minutes at 25℃. It can be cured at room temperature or heated, with full curing at 80℃ taking 4-5 hours. It boasts a dielectric strength of ≥25 kv/m-1, a dielectric constant of 3.0 (1.2MHz), and a volume resistance of ≥1×1015 Ω. All parameters (hardness, viscosity, operation time) can be customized to match EV charger requirements.
Product Features & Advantages
- Excellent flame retardancy: Forms a reliable flame-retardant system, preventing fire hazards caused by overheating in EV chargers, ensuring user and equipment safety. - Superior insulation performance: High dielectric strength and volume resistance, avoiding short circuits in high-voltage charger circuits, guaranteeing stable charging. - Flexible curing options: Cures at room temperature or by heating, adapting to different EV charger production processes, improving manufacturing efficiency. - Environmentally protective: Waterproof, moisture-proof, mold-proof and dust-proof, protecting charger components from harsh environments, extending service life. - Low shrinkage & no corrosion: Cures without exotherm, no damage to charger PCBs and electronic components, ensuring product integrity. - Good thermal conductivity: Dissipates heat generated during fast charging, preventing component overheating and maintaining stable performance. - Chemical resistance: Resists common industrial chemicals, non-yellowing and weather-resistant, suitable for long-term use.
How to Use
1. Before mixing, fully stir Part A and Part B separately in their respective containers to ensure uniform consistency. 2. Mix Part A and Part B at a 1:1 weight ratio, stirring thoroughly for uniform mixing. 3. Degas the mixed silicone at 0.08MPa for 3 minutes to remove air bubbles before pouring. 4. Cure at room temperature or heat; in low-temperature environments (winter), proper heating can accelerate curing to ensure stable performance.
