Case Overview

This case demonstrates how HN-8806A/B silicone potting compound from Shenzhen Hanast New Materials Co., Ltd. safeguards battery energy storage systems (BESS) across Europe. As Germany, the Netherlands, Scandinavia and Southern Europe expand grid-scale and home storage capacity, BMS manufacturers need encapsulation that performs from freezing Nordic winters to warm Mediterranean summers. HN-8806A/B offers the wide temperature range, flame retardancy and long-term reliability that European energy storage projects require.

Customer Background

The customer is a European energy storage system integrator producing battery management systems (BMS), power conversion units and monitoring electronics for residential and commercial BESS installations. Its operating environments include:

• Winter ambient temperatures below -20°C in Northern Europe, with storage cabinets in unheated spaces;
• Summer peaks above 35°C inside containerised battery energy storage systems;
• Strict EU safety, environmental and recycling regulations, including RoHS compliance;
• High fire-safety scrutiny for lithium battery installations in residential and urban areas;
• Continuous charge-discharge cycling that generates heat inside enclosures.

Challenge

Battery systems place unique demands on encapsulation materials. Rigid resins can crack at low temperatures and transfer stress to BMS boards, while poorly insulating materials risk leakage currents in high-voltage battery stacks. The integrator required a potting compound that stays flexible in cold weather, conducts heat away from power electronics, meets strict flame-retardant standards, and does not corrode sensitive battery monitoring circuits.

Solution: HN-8806A/B Silicone Potting Compound

HN-8806A/B is a two-component, addition-cure silicone potting compound that cures into a soft, high-performance elastomer with no exotherm and no corrosive by-products - a critical advantage when potting directly around battery sensing electronics. Key properties for this project:

Why HN-8806A/B Suits European Energy Storage

• Cold-climate flexibility: the elastomer remains functional down to -50°C, preventing brittle cracking in Nordic winters;
• Battery-safe chemistry: no corrosive by-products during cure protects cell tabs, busbars and sensing wires from chemical attack;
• No exothermic cure: unlike some resins, HN-8806A/B releases no heat while curing, avoiding hot spots near battery cells;
• Thermal management: ≥0.76 W/m·K conductivity moves heat from BMS power stages to cabinet cooling;
• Electrical reliability: high volume resistivity minimises leakage current in high-voltage battery stacks;
• Fire safety: UL 94 V-0 rating supports compliance with EU battery and building fire-safety requirements;
• Environmental compliance: RoHS compliance aligns with EU directives and customer sustainability targets;
• Automated production: 1:1 ratio and 18-24 minute pot life integrate cleanly into BMS assembly lines.

Results

• BMS boards encapsulated with HN-8806A/B passed cold-chamber tests at -40°C with no cracking or delamination;
• Leakage current readings remained stable in high-voltage battery stacks during long-term monitoring;
• Heat-accelerated curing at 80°C for 12 minutes allowed just-in-time production of control modules;
• Fire-safety documentation supported approvals for residential and commercial storage projects;
• Field service teams reported no moisture-related failures after two years of European operation.

Packaging and Compliance

HN-8806A/B is supplied in 25 kg plastic barrels per component, is RoHS compliant and is classified as non-dangerous goods, simplifying EU import and warehousing. Recommended storage at 5-25°C in sealed containers preserves the full 6-month shelf life.

Conclusion

European energy storage demands materials that stay reliable from Arctic cold to summer heat while meeting the world's strictest safety and environmental rules. HN-8806A/B silicone potting compound delivers the flexibility, insulation and flame retardancy that BMS and power electronics need.
