LED Power Supply Potting Compound HN-8808B/W - High Thermal Conductivity for Long Life Product Overview for Silicone Potting Compound: The lifespan of an LED driver is critical to the overall light's reliability. The HN-8808 series potting compounds significantly reduce internal temperatures by efficiently transferring heat from hotspots (like MOSFETs and rectifiers) via their high thermal conductivity (0.5 W/M·K). The comprehensive waterproof, moisture-proof, insulating, and
