22 kV/mm High Dielectric Strength Electrical Epoxy Potting Compound for Capacitor Transformer Sensor Encapsulation

22 kV/mm High Dielectric Epoxy Potting Compound HN-5508A/B – Capacitor, Transformer & Sensor Encapsulation

Hanast HN-5508A/B is a high dielectric strength (22 kV/mm) epoxy potting compound purpose-engineered for electrical and electronic components requiring superior high voltage insulation. Formulated as a two-component black epoxy system, it delivers exceptional dielectric protection for capacitors, transformers, industrial sensors, and LED modules operating in high-voltage environments.

Key Features

• 22 kV/mm Dielectric Strength – Industry-leading electrical insulation performance that prevents current leakage, arc-over, and short circuits in high voltage electronic assemblies
• Capacitor & Transformer Grade – Specifically formulated for potting and sealing power capacitors, high-voltage transformers, flyback transformers, and inductive components requiring maximum dielectric protection
• Industrial Sensor Compatible – Low-stress cure profile protects sensitive sensor elements and transducers during encapsulation while providing full environmental sealing
• Moisture-Proof & Vibration Resistant – Forms a rugged, chemical-resistant protective barrier that shields components from humidity, water ingress, mechanical shock, and industrial contaminants
• High Hardness 80-90 Shore D – Cures to a rigid, durable finish that prevents physical tampering and provides long-term structural integrity in demanding industrial environments
• Wide Operating Temperature (-40°C to 130°C) – Maintains stable dielectric properties across extreme temperature ranges for outdoor, automotive, and industrial applications
• RoHS & REACH Compliant – Meets international environmental and safety standards for global electronics supply chains

Technical Specifications

Recommended Applications

• Power Capacitor Encapsulation – High dielectric potting for film capacitors, power factor correction capacitors, and energy storage capacitors requiring 22 kV/mm insulation protection
• Transformer & Coil Potting – Complete encapsulation of power transformers, high-voltage flyback transformers (FBT), ignition coils, and inductive components with critical dielectric requirements
• Industrial Sensor Protection – Low-stress potting for temperature sensors, pressure transducers, proximity sensors, and industrial measurement devices operating in harsh factory environments
• LED Module Sealing – Moisture-proof encapsulation for outdoor LED display modules, LED drivers, and lighting power supplies exposed to weather and condensation
• High Voltage Electronic Assemblies – Dielectric protection for power supplies, inverters, motor drives, and high-voltage PCB assemblies

Application Guidelines

1. Ensure all substrates are clean, dry, and free of contaminants
2. Mix Part A and Part B thoroughly according to the product-specific ratio by weight
3. Vacuum degas for 3-5 minutes to eliminate entrapped air bubbles
4. Pour within 30-40 minute pot life at 25°C
5. Cure at room temperature (12-24h full cure) or heat at 60°C (2-3h) for faster throughput
