UL94 V-0 Clear Epoxy Potting Compound 5:1 Two Component Encapsulant for EV Onboard Charger Module
UL94 V-0 Clear Epoxy Potting Compound 5:1 Two Component Encapsulant for EV Onboard Charger Module
HN-5508AB is a clear two-component epoxy potting compound with a 5:1 mix ratio, specially formulated for EV onboard charger (OBC) module and high voltage power electronics encapsulation. The halogen-free formulation delivers UL 94 V-0 flame retardancy, stable electrical insulation and excellent moisture protection under continuous high voltage operation, making it a reliable choice for electric vehicle charging systems.
Key Features
- UL 94 V-0 flame retardant: halogen-free formulation that protects EV onboard charger modules against fire risk and meets international safety requirements.
- Clear / transparent appearance: cured surface enables easy visual inspection of encapsulated components and void-free quality control.
- 5:1 two-component system: convenient dispensing with low mix error rate, suitable for automated potting lines.
- Wide temperature range: stable performance from -40℃ to 150℃, covering automotive thermal cycling requirements.
- High electrical insulation: dielectric strength 20-22 kV/mm protects OBC power stages from arcing and partial discharge.
- Low water absorption: <0.03% water absorption keeps insulation stable in humid and condensing environments.
- ROHS SGS compliant: environmentally friendly material meeting automotive and electronics compliance needs.
