Latest company case about Shenzhen Hanast New Material co.,LTD Certifications

HN-8830A/B is a two-component, addition-cure (platinum) thermally conductive silicone potting compound with 3.0 W/m·K thermal conductivity. This B2B case study examines how a manufacturer of home appliance controllers — washing machines, refrigerators and air conditioners — used HN-8830A/B to pot control boards for reliable heat dissipation, electrical insulation and moisture protection.

Appliance controllers combine microprocessors, relays and power components on one board, often in humid or hot environments. Manufacturers require:

• Effective heat dissipation from power components and relays;
• Electrical insulation for safety and EMC reliability;
• Moisture and humidity protection (kitchens, laundry, outdoor AC units);
• Flame retardancy (UL94 V-0) for household safety compliance;
• Void-free encapsulation of dense, uneven boards with a self-levelling compound.

HN-8830A/B flows into complex boards and cures to a flexible, insulating elastomer that resists heat and moisture. With 3.0 W/m·K conductivity and a −40°C to 200°C range, it protects appliance controllers against thermal and environmental stress, while UL94 V-0 meets safety requirements.

1. Pre-mix Component A and shake Component B until homogeneous.
2. Weigh A and B accurately in a 1:1 ratio by weight.
3. Mix until uniformly coloured, scraping the container walls and bottom.
4. Vacuum-degas for void-sensitive controller boards.
5. Pour into the clean, dry housing within the pot life.
6. Cure 4–8 h at room temperature or 30 min at 80°C.

• Improved heat dissipation extended the life of appliance controllers;
• Robust insulation and moisture protection reduced field failures;
• UL94 V-0 flame retardancy supported household safety compliance;
• Self-levelling flow gave void-free potting of dense boards;
• The long pot life suited mixed-batch production lines.

What is the thermal conductivity of HN-8830A/B? 3.0 ± 0.1 W/m·K.

Is it suitable for home appliance controllers? Yes — it is widely used for potting appliance control boards and power modules.

What is the mix ratio? 1:1 by weight (A:B).

Is it flame retardant? Yes — UL94 V-0.

For home appliance controller manufacturers, HN-8830A/B provides high thermal conductivity (3.0 W/m·K), UL94 V-0 flame retardancy and dependable −40°C to 200°C performance with simple 1:1 processing.
