Industrial Controller & Micro Inverter Silicone Potting Compound Manufacturer | 3.0 W/m·K Thermal Addition Silicone (HN-8830)

Industrial Controller & Micro Inverter Silicone Potting Compound Manufacturer | 3.0 W/m·K Thermal Addition Silicone (HN-8830)

Product Overview:

Shenzhen Hanast New Materials Co., Ltd. manufactures HN-8830A/B, a premium addition-cure (platinum-catalyzed) 3.0 W/m·K high thermal conductivity silicone potting compound developed for industrial PLC controllers, frequency converters, micro inverters, and heavy-duty power circuit boards. Featuring a 1:1 mix ratio by weight, a density of 2.95 g/cm³, and self-leveling viscosity (11,000 mPa·s), HN-8830 ensures complete void-free filling in deep-section PCB potting applications.

HN-8830 maintains flexible elastomeric protection (Shore A 35 ± 8) across continuous service temperatures from -40°C to +200°C, offering high dielectric strength, high volume resistivity (≥ 1.0 × 10¹⁴ Ω·cm), and UL 94 V-0 flame retardancy. It cures at room temperature (4–8 hours at 25°C) or via heat acceleration (30 minutes at 80°C). Packaged in 50 kg sets (25 kg A + 25 kg B plastic barrels), we provide factory-direct supply with complete GHS SDS/MSDS for non-dangerous sea freight and Form E / RCEP certificates.

5. Frequently Asked Questions (FAQ) Module

Q1: What is the recommended application procedure to avoid uncured surface defects?

A: Pre-mix Component A thoroughly before use as dense thermal fillers may settle during storage. Shake or stir Component B well. Weigh A and B accurately at a 1:1 ratio by weight using a precision electronic scale. Mix thoroughly, scrape container walls, and optionally vacuum degas for void-free results. Ensure components do not contact organotin, sulfur, amines, or flux residues to prevent platinum catalyst inhibition.

Q2: What packaging sizes and export shipping options are available for bulk buyers?

A: HN-8830 is supplied in 50 kg kit sets (25 kg Component A + 25 kg Component B plastic barrels). It carries a shelf life of 6 months when stored between 5–25°C in sealed original containers. Classified as non-dangerous general chemical goods, it is easy and cost-effective to ship via standard sea freight containers with our SDS/MSDS and Form E / RCEP documentation.
