Product Overview
Our Control Board Electronic Potting Silicone Compound is a professional low-viscosity, flame-retardant two-component addition-curing organic silicone potting material, a key part of HONG YE SILICONE’s full silicone product matrix. Model HY-9315 is tailored for control board protection, designed to solve control board pain points—heat accumulation, signal interference, moisture damage and component loosening. It can cure at room temperature or with heating (faster at higher temperatures), forming a soft rubber-like protective layer, providing comprehensive insulation, waterproofing and fixation for control boards, far exceeding ordinary Electronic Potting Compound in control board adaptability. Product Features & Advantages
1. Control board-specific precise导热: Thermal conductivity ≥0.8 W(m·K), efficiently dissipates heat from control board chips and components, avoids overheating-induced malfunctions, ensuring stable and accurate control signals.
2. Superior safety performance: UL94-V0 flame retardancy (highest level for control boards), IP65 waterproof rating, and high insulation (volume resistivity ≥1.0×10¹⁶ Ω·cm, dielectric strength ≥25 kv/mm), eliminating fire and short-circuit risks.
3. Wide temperature adaptability & anti-impact: Operates stably from -60℃ to 220℃, adapts to various working environments; cures into soft rubber, with excellent impact resistance, protecting fragile control board components from collision damage.
4. Easy operation & production-friendly: 1:1 weight mixing ratio (easy to measure), low viscosity and good leveling; optional deaeration at 0.08MPa for 5 minutes ensures bubble-free potting, suitable for automated control board production lines.
5. Strong compatibility & customization: Adheres well to PC, PP, ABS, PVC and metals, compatible with all types of control board substrates; hardness, viscosity and operable time can be customized to match different control board sizes and processes.
Technical Specifications (Model HY-9315)
This product is a two-component control board potting silicone: Component A and B are both liquid, each with a viscosity of 500±100 cps. Mixing ratio is 1:1 by weight, mixed viscosity 500±100 cps, operable time 0.5-2 hours. Curing time is 4-5 hours at room temperature or 20 minutes at 80℃. After curing, it reaches Shore A hardness 15±5, thermal conductivity ≥0.8 W(m·K), dielectric strength ≥25 kv/mm, dielectric constant 3.0～3.3 (1.2MHz), volume resistivity ≥1.0×10¹⁶ Ω·cm, linear expansion coefficient ≤2.2×10⁻⁴ m/(m·K), UL94-V0 flame retardancy. Other models and customizable parameters are available on request.
How to Use
1. Preparation: Fully stir Component A and B separately in their respective containers to ensure uniform material composition, critical for stable thermal conductivity and insulation performance of control boards.
2. Mixing: Blend Component A and B strictly according to 1:1 weight ratio, stir thoroughly to guarantee consistent curing and protective performance for control board components.
3. Deaeration (Optional): After mixing evenly, place the mixed liquid into a vacuum container and deaerate for 5 minutes under 0.08MPa to remove air bubbles, avoiding heat accumulation and signal interference caused by bubbles.
4. Potting & Curing: Pour the treated silicone onto control boards; cure at room temperature (8 hours) or heat (80～100℃ for 15 minutes, recommended in winter). For thick application, extend curing time appropriately.
Application Scenarios
