Wevo Launches Polyurethane Potting Compound for EV Battery Management PCBs
The WEVOPUR 60210 FL T compound handles up to 800 V systems using a dam-and-fill application method.
Wevo has developed WEVOPUR 60210 FL T, a polyurethane compound designed for selective potting of multilayer printed circuit boards in automotive battery management systems used in electric vehicles.
What Happened
The new compound is applied using the dam-and-fill method and is engineered for boards that monitor and control voltages up to 800 V. The material has a Shore hardness of D 40 to 50, thermal conductivity of 0.8 W/m·K, and dielectric strength exceeding 20 kV/mm. According to Wevo, the compound absorbs shocks, vibrations and stresses from temperature fluctuations while moving heat through the assembly to reduce temperature differences between components. The cured material fixes components in place, is formulated to prevent electrochemical corrosion, protects against moisture and forms a durable bond designed to help prevent delamination.
Why It Matters
Battery management systems handle increasingly complex diagnostic, communication and safety functions that push up integration density on their circuit boards. These boards must withstand mechanical stress, changing environmental conditions and high operating temperatures in electric vehicles. Potting compounds like WEVOPUR 60210 FL T shield automotive electronics from vibration, moisture and heat while selective application keeps connectors and testing points accessible for service and verification.
The Bottom Line
Wevo formulated the system to run on standard two-component mixing and dosing equipment, which the company says reduces work involved in material qualification, storage and process management. The flow behavior and thixotropy are tuned so the barrier holds its shape during application while the filler wets protected areas without trapping air pockets.
