Laatste zaak van het bedrijf over HN-8806A/B Silicone Potting Compound for New Energy Equipment: Southeast Asia EV Charging Field Case

Case Overview

This case presents how HN-8806A/B two-component silicone potting compound from Shenzhen Hanast New Materials Co., Ltd. delivers dependable protection for new energy electronic equipment operating across Southeast Asia. As regional economies accelerate the adoption of electric vehicles, solar power and battery energy storage, manufacturers in Vietnam, Thailand, Indonesia, Malaysia and the Philippines increasingly need encapsulation materials that survive tropical conditions. With a wide operating temperature range of -50°C to 250°C, thermal conductivity and UL 94 V-0 flame retardancy, HN-8806A/B is engineered for power modules, control units and circuit boards that demand reliable insulation and heat dissipation.

Customer Background

The customer is a fast-growing new energy equipment manufacturer based in Southeast Asia, producing EV onboard chargers, DC-DC converters, solar inverters, charging piles and energy storage systems. Its production lines and field installations face demanding tropical conditions:

  • High ambient temperatures of 30-45°C year-round with direct sunlight exposure;
  • Heavy monsoon rainfall and relative humidity frequently above 85%;
  • Coastal installations exposed to salt mist and corrosive air;
  • Continuous vibration and thermal cycling in EV and power applications;
  • Strict safety and environmental requirements, including UL 94 V-0 and RoHS.

Challenge

Conventional rigid potting materials cracked under thermal cycling and transferred mechanical stress to sensitive components, while slow-curing compounds limited production output. The customer needed a soft, stress-relieving encapsulant that could cure quickly, dissipate heat from high-power modules, seal against monsoon humidity, and still pass stringent flame-retardant certification.

Solution: HN-8806A/B Silicone Potting Compound

Hanast recommended HN-8806A/B, an addition-cure, two-component silicone potting compound that cures at room temperature or with heat into a high-performance elastomer. It releases no heat or by-products during cure, causes no corrosion to sealed components, and produces no pollution to the surrounding environment. Key technical data:

Thermal conductivity ≥ 0.76 W/m·K
Volume resistivity 1.0 * 10¹&sup6 Ω·cm
Dielectric strength 25-30 kV/mm
Flame retardancy UL 94 V-0; RoHS compliant
Operating temperature range -50°C to +250°C
Cure shrinkage Extremely low; supports deep-section curing

Why HN-8806A/B Suits New Energy Applications in Southeast Asia

  • Tropical heat resistance: reliable performance from -50°C to 250°C covers both equatorial heat and overnight temperature swings;
  • Thermal management: ≥0.76 W/m·K thermal conductivity pulls heat away from EV chargers, inverters and battery management boards;
  • Humidity and moisture sealing: excellent moisture-proofing protects electronics through monsoon seasons and coastal salt mist;
  • Vibration and thermal-cycling protection: the soft Shore A 45 elastomer absorbs shock and stress instead of cracking like rigid resins;
  • High-voltage insulation: 25-30 kV/mm dielectric strength and 1.0 * 10¹&sup6 Ω·cm volume resistivity;
  • Safety and compliance: UL 94 V-0 flame retardancy and RoHS compliance meet regional certification needs;
  • Production efficiency: 1:1 mix ratio, 18-24 minute pot life and 80°C/12-minute heat cure fit automated dispensing lines;
  • Deep-section curing: extremely low shrinkage and no cure by-products enable thick encapsulation of large power modules.

Results

After switching to HN-8806A/B, the customer achieved measurable improvements:

  • Encapsulated modules withstood thermal cycling and vibration without cracking, reducing field failures;
  • Production throughput improved significantly using the heat-accelerated cure at 80°C for 12 minutes;
  • High-voltage insulation and flame-retardant performance passed end-customer and regional certification requirements;
  • Moisture-related failures were eliminated during monsoon-season field operation;
  • Free sample support and flexible MOQ accelerated design-in and pilot production.

Packaging, Storage and Logistics

HN-8806A/B is supplied in 25 kg plastic barrels for each component (50 kg/set kit). Store in tightly sealed original containers at 5-25°C in a cool, dry, ventilated area, away from direct sunlight; shelf life is 6 months from the date of manufacture. The product is classified as non-dangerous goods for transportation, simplifying cross-border delivery to Southeast Asia.

Conclusion

For new energy equipment designed for Southeast Asia, reliable encapsulation is not optional - it is the difference between field success and premature failure. HN-8806A/B silicone potting compound delivers the heat resistance, thermal management, moisture sealing and mechanical protection that EV charging, solar and energy storage products demand.
