Product Overview
Our Electronic Potting, also called encapsulation silicone or electronic silicone, is a low-viscosity, dual-component RTV Silicone Encapsulant specially engineered for drone flight controllers—the core control unit of drones. As a professional supplier of Electronic Potting Compound and high-purity silicone solutions, we optimize this product for drone working scenarios: it bonds perfectly to PC, PP, ABS, PVC and various metals, with excellent waterproof, insulation and shock absorption performance. It effectively protects flight controller circuit boards and electronic components from moisture, dust, vibration and outdoor harsh conditions, ensuring precise flight control and stable operation. Technical Specifications
Our Electronic Potting (Model HY-9325) has stable performance with fully customizable parameters; key specifications are as follows: it is a dual-component liquid silicone (A and B), both appearing as viscous liquid with a viscosity of 500±100 cps. 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 minutes, full curing takes 24 hours at room temperature. After curing, hardness is 25±2 Shore A, thermal conductivity ≥0.2 W(m·K), dielectric strength ≥25 kV/mm, dielectric constant 3.0~3.3 (1.2MHz), volume resistivity ≥1.0×10¹⁶ Ω·cm, flame retardancy meets UL94-V1. Shelf life is 1 year, non-hazardous for general chemical transportation.
Product Features & Advantages
- Excellent Waterproof & Insulation: Superior waterproof and insulation performance, effectively isolating moisture and dust, protecting drone flight controllers from damage in outdoor rainy or humid environments.
- Fast Room-Temperature Deep Curing: Basic curing in 3-5 minutes, full curing in 24 hours, supporting rapid mass production of drone flight controllers and improving production efficiency.
- Strong Shock Resistance: Cured into flexible rubber, able to absorb vibration and impact during drone flight and landing, protecting fragile flight controller components from damage.
- Low Viscosity & Good Fluidity: Easy to pour and fill tiny gaps of flight controller components, ensuring full encapsulation and reliable protection.
- UL94-V1 Flame Retardancy: High-level flame retardancy, effectively preventing fire risks, ensuring the safety of drone flight controllers during operation.
- Wide Compatibility: Excellent adhesion to PC, PP, ABS, PVC and various metals, perfectly compatible with drone flight controller materials, ensuring tight bonding.
How to Use (Step-by-Step)
- Pre-Mix Preparation: Thoroughly stir Component A to mix settled black pigment 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 glue 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 glue into drone flight controllers, cure at room temperature. Proceed to the next process after basic curing (3-5 minutes), and ensure full curing (24 hours) for optimal protection; environment temperature and humidity affect curing speed.
