Waterproof Clear Epoxy Potting Compound 5:1 Two Component Encapsulant for Underwater Electronics
Waterproof Clear Epoxy Potting Compound 5:1 Two Component Encapsulant for Underwater Electronics
HN-5508AB is a clear two-component epoxy potting compound with a 5:1 mix ratio, specially formulated for underwater electronics, marine equipment and water-exposed electronic module encapsulation. It combines UL 94 V-0 flame retardancy, excellent thermal shock resistance, high dielectric strength and low water absorption, protecting sensitive circuits from moisture ingress and pressure cycling in underwater and high-humidity environments.
Key Features
- Waterproof protection: low water absorption and tight sealing performance keep underwater electronics safe from moisture, condensation and splash.
- Clear / transparent appearance: cured surface enables easy visual inspection of encapsulated components and quality control.
- 5:1 two-component system: convenient dispensing with low mix error rate, suitable for automated potting lines.
- UL 94 V-0 flame retardant: halogen-free formulation meets international safety requirements.
- Wide temperature range: stable performance from -40℃ to 150℃ with excellent thermal shock resistance.
- High electrical insulation: dielectric strength 20-22 kV/mm protects circuits from arcing and leakage.
- ROHS SGS compliant: environmentally friendly material meeting electronics compliance needs.
