ELAPLUS SIPA 1850 High Thermal Conductivity & Anti-Poisoning Silicone Potting Compound – Recommended for LED Power Supplies

In LED lighting, power adapters, outdoor lamps, industrial lighting, street light modules, landscape lighting and new energy electronic devices, LED drivers are core components that determine the overall stability and service life of luminaires. During long-term operation, LED drivers generate continuous heat. They are also exposed to moisture, dust, thermal cycling, vibration, impact and outdoor aging. Without adequate internal protection, risks such as overheated components, degraded insulation, failed solder joints, water ingress and short circuits, as well as compound cracking may occur. Therefore, selecting proper potting compound has become critical to improving the reliability of LED drivers. For LED driver potting applications, ELAPLUS recommends SIPA 1850 Two-Component Silicone Potting Compound. Featuring high thermal conductivity, high viscosity with thixotropy and excellent anti-poisoning performance, this product offers thermal conductivity ranging from 0.7 to 4.0 W/m·K, catering to heat dissipation requirements of LED power supplies with different power ratings. 1. Why Do LED Drivers Need Potting? An LED driver consists of capacitors, inductors, transformers, MOSFETs, rectifier bridges, IC chips, resistors, terminals and PCB circuits. Power components generate constant heat during operation, and accumulated heat will shorten the service life of electronic parts. Main functions of LED driver potting compound: ■ Heat Conduction & Dissipation: Transfer heat from power components to enclosures or heat dissipation structures. ■ Water & Moisture Resistance: Prevent moisture ingress and reduce risks of short circuit and corrosion. ■ Electrical Insulation: Protect PCBs and components for enhanced operational safety. ■ Vibration Damping: Mitigate impact from vibration during transportation, installation and use. ■ Dustproof & Sealing: Ideal for outdoor lamps, street lights and industrial lighting fixtures. ■ Service Life Extension: Improve long-term operational reliability of LED drivers. For outdoor LED power supplies, street light drivers, industrial light power units, landscape light power supplies and high-power LED driver modules, the potting compound shall not only achieve full filling,…
