Quick Summary

A Southeast Asia energy storage system (ESS) integrator eliminated a combined heat-dissipation and electrical-insulation challenge by adopting Hanast HN-8820A/B as its potting material for energy storage system (ESS). The two-component addition-cure silicone (2.0 W/m·K, 1:1 mix ratio by weight) reduced module temperature rise by 12°C and passed IP67 and UL94 V-0 testing.

Background

The client is an overseas energy storage system integrator serving utilities, industrial parks, and commercial buildings across Indonesia, Malaysia, Thailand, and the Philippines. Its containerized battery storage products combine densely packed lithium battery modules with liquid-cooled cold plates, and must operate continuously in ambient temperatures that regularly exceed 35°C. Reliable thermal management and electrical insulation are essential to safety and service life.

Challenge

• Battery modules ran above target temperatures under peak load, creating hotspots.
• Rigid epoxy potting was too hard — it cracked under long-term thermal cycling between hot days and cool nights.
• The previous material’s thermal conductivity was too low to move heat from cells to cold plates.
• Moisture ingress threatened insulation reliability in the tropical climate.
• The material had to remain flexible and stable across a wide temperature range.

Hanast Solution

Hanast recommended HN-8820A/B, a two-component addition-cure (platinum-catalysed) silicone potting compound with a thermal conductivity of 2.0 ± 0.1 W/m·K and a 1:1 mix ratio by weight. As a UL94 V-0 certified potting compound for high-voltage energy storage, it provides flame-retardant protection, low viscosity (5,000–8,000 mPa·s) for easy pouring and self-levelling, and a cured elastomer that stays flexible across −40 °C to 200 °C.

Typical Applications

HN-8820A/B is engineered for demanding power-electronics protection. Across energy storage and solar power applications it is used as:

• Potting material for energy storage system (ESS)
• Flame-retardant thermal conductive silicone for photovoltaic inverters
• UL94 V-0 certified potting compound for high-voltage energy storage

Result / Data

• Module temperature rise reduced by 12°C under high load.
• Cell-to-cell temperature variation narrowed by 35%.
• The assembled module passed IP67 water- and dust-resistance testing.
• Material meets UL 94 V-0 flame retardancy.
• No cracking after extended thermal cycling; projected service life extended by more than two years.

Client Feedback

“The 1:1 addition-cure silicone solved both our cracking and our heat problems. Our modules now run cooler and more evenly," said the client’s engineering lead.
