Thermal conductive potting solution for industrial controllers

2026-01-15

—— A reliable and removable protective option after curing. In applications such as industrial automation, smart manufacturing, and energy control, industrial controllers operate in environments with high loads, high temperature rises, strong vibrations, and complex conditions for extended periods.The key challenge in the potting design of industrial controllers lies in balancing efficient heat dissipation with the removability for future maintenance, repair, and upgrades. Addressing this industry pain point, ELAPLUS has launched SIPA 1850, a low-stress, removable thermal conductive potting adhesive, providing a more reliable and flexible potting solution for industrial controllers. ❌ Non-detachable after curing, making repair essentially equivalent to scrapping ❌ High internal thermal stress, prone to cracking of solder joints and components ❌ Decreased reliability after thermal cycling ❌ Not conducive to product upgrades and rework.
