PCB waterproof potting solution for new energy vehicle charging gun

With the rapid popularization of new energy vehicles, charging guns, as external connection components that are used frequently, are exposed to rain, moisture, temperature changes, and complex outdoor conditions for extended periods. Their internal PCB boards not only carry out signal transmission and current control functions but also directly affect the safety, stability, and service life of the entire gun.Once the PCB protection is not in place, it is extremely prone to: The intrusion of moisture leads to electrical leakage and short circuits. Humid environments cause a decline in insulation performance. Temperature cycling results in stress concentration and solder joint failure. Therefore, higher requirements are placed on the potting materials inside PCBs.Key Challenges High waterproof grade requirements: Long-term stability to achieve IP67 moisture resistance + reliable electrical insulation performance Possess a certain adhesive strength with PC housing and wiring harness to prevent vibration and loosening Process-friendly: Manual potting is less prone to bubbling, with feasible rework No stress, cracking, or corrosion during long-term use Main recommended solution for electronic components: SIPC 1815 silicone potting adhesive SIPC 1815 is a two-component condensation de-alcoholized silicone potting adhesive, specifically designed for applications such as new energy vehicle charging guns and outdoor electronic modules.Product advantages:✔ Excellent waterproof performance, easily meeting IP67 requirements ✔ Good fluidity, easy to spread and spread without entraining bubbles when manually pouring glue ✔ Repairable design, reducing maintenance and after-sales costs ✔ Low curing shrinkage rate, no corrosion, no internal stress, protecting PCB and solder joints ✔ Stable high-temperature electrical insulation performance, adapting to temperature rise environment during charging process ✔ Good adhesion to PC housing and wiring harness, taking into account both sealing and structural fixation ✔ Waterproof, moisture-proof, and high reliability for long-term use View SIPC 1815 details 👉 Especially suitable for charging gun products with high requirements…
