High-Voltage Insulation: Protecting Ignition Coils and Chargers with HN-9130 Epoxy

Ignition systems and EV fast-chargers operate under high voltage stress. A single micro-crack in the insulation can lead to catastrophic electrical arcing.

Maximum Dielectric Protection:
The HN-9130A/B High Thermal Conductivity Potting Compound is specifically designed for high-voltage encapsulation.
• Superior Insulation: With a dielectric strength of >22 Kv/mm, it provides a safe, impenetrable barrier for ignition coils and power modules.
• Structural Integrity: The Shore-D 83 hardness creates a "stone-like" casing that protects internal windings from physical deformation and moisture-induced shorts.
• Thermal Conductivity (3.0 W/m·K): High-voltage components generate localized hot spots; HN-9130 effectively spreads this heat, preventing insulation breakdown.
