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

This case study shows how a power-electronics manufacturer serving Southeast Asia improved the reliability of its power modules and LED drivers with HN-8810A/B thermally conductive silicone potting compound from Shenzhen Hanast New Materials. The 1:1 addition-cure (platinum) system combines 1.0 W/m·K thermal conductivity with excellent electrical insulation and UL94 V-0 flame retardancy.

Power modules pack high currents and heat into small housings. The producer needed a potting material that could solve several problems at once:

• dissipating heat away from power components and modules;
• insulating live parts to prevent short circuits;
• sealing against humidity and moisture in a hot, humid climate;
• meeting a flame-retardancy requirement (UL94 V-0);
• a low-viscosity, self-levelling compound that fully fills complex housings;
• satisfying international safety and flammability standards required by export buyers.

HN-8810A/B is a two-component addition-cure thermally conductive silicone potting compound with a simple 1:1 mix ratio by weight. It cures at room temperature or with heat acceleration (80°C for 10–20 min), and the cured elastomer keeps its rubber elasticity over a wide temperature range.

1. Pre-mix: stir Components A and B separately so settled filler is uniformly dispersed.
2. Weighing: accurately weigh A and B in a 1:1 ratio by weight.
3. Mixing: mix thoroughly until the colour is uniform; avoid overly large batches by hand.
4. Degassing: vacuum-degas to remove air entrapped during mixing.
5. Potting: pour the degassed compound into the clean, dry device to complete potting.
6. Curing: cure at room temperature, or heat at 80°C for 10–20 min; complete potting within the working time.

• Effective heat transfer kept power-module temperatures under control;
• Excellent insulation protected live parts reliably;
• Waterproof, moisture-proof sealing suited the humid Southeast Asian climate;
• UL94 V-0 rating met the flame-retardancy requirement;
• Low viscosity and self-levelling behaviour gave void-free potting in complex housings;
• Room-temperature or fast 80°C heat cure fitted both small-batch and production-line use.

For power-module and LED-driver makers in Southeast Asia, HN-8810A/B delivers combined heat dissipation, insulation and moisture protection in a single easy-to-process compound. Shenzhen Hanast New Materials supports partners with samples, application guidance and technical data.
