LED Driver & Outdoor Lighting Thermal Silicone Potting Compound Manufacturer | 3.0 W/m·K High Heat Dissipation (HN-8830)

LED Driver & Outdoor Lighting Thermal Silicone Potting Compound Manufacturer | 3.0 W/m·K High Heat Dissipation (HN-8830)

Product Overview:

Shenzhen Hanast New Materials Co., Ltd. is an ISO 9001 certified China chemical manufacturer producing HN-8830A/B, a high-performance 3.0 W/m·K high thermal conductivity silicone potting compound engineered for outdoor LED driver power supplies, street light modules, architectural fixtures, and high-bay lighting controls. Featuring a 1:1 mix ratio by weight and low mixed viscosity (11,000 mPa·s), HN-8830 offers excellent self-leveling fluidity to fill deep sections around densely packed power components.

HN-8830 provides long-term weatherability, superior electrical insulation (volume resistivity ≥ 1.0 × 10¹⁴ Ω·cm), and UL 94 V-0 flame retardancy across continuous operating temperatures from -40°C to +200°C. It offers flexible curing schedules: 4–8 hours at 25°C room temperature or rapid heat acceleration in 30 minutes at 80°C. Supplied in 50 kg sets (25 kg Component A + 25 kg Component B plastic barrels), we provide complete GHS MSDS/SDS for non-dangerous goods sea freight and Form E / RCEP origin certification.

5. Frequently Asked Questions (FAQ) Module

Q1: Why is 3.0 W/m·K thermal conductivity critical for high-power LED driver potting?

A: High-wattage LED drivers generate substantial internal heat in compact metal housings. HN-8830’s high thermal conductivity of 3.0 ± 0.1 W/m·K rapidly transfers heat away from power MOSFETs and transformers to the aluminum casing, drastically reducing component operating temperatures and extending fixture lifespans.

Q2: How does the 1:1 mix ratio benefit automated LED driver production lines?

A: A 1:1 mix ratio by weight allows for easy machine calibration with minimal error margins compared to 10:1 systems. Combined with a flexible pot life of 60–180 minutes and a low mixed viscosity of 11,000 mPa·s, HN-8830 flows easily around complex circuitry without trapping air bubbles.
