— A range of silicone conformal coatings, comprehensively enhancing the reliability and safety level of BMS. With the rapid development of new energy vehicles, energy storage systems, and high-end industrial equipment, BMS (Battery Management System) is operating in complex environments such as high humidity, high temperature, salt spray, dust, and electrochemical corrosion for extended periods.
Once the PCB board becomes damp, experiences creepage, or is corroded, it will directly affect the safety and lifespan of the battery system.
Therefore, three-proofing coating (moisture-proof, mold-proof, and salt spray-proof) has become a standard process for BMS electronic protection. Silicone three-proofing coating, with its excellent flexibility, electrical insulation, and environmental adaptability, has become the mainstream material choice for BMS coating.
Analysis of core requirements for BMS three-proofing coating In BMS applications, three-proofing coating materials typically need to meet the following requirements simultaneously:
Excellent moisture resistance, salt spray resistance, and chemical corrosion resistance Long-term stable electrical insulation performance Resistance to thermal shock, avoiding coating cracking caused by thermal expansion and contraction Fast surface drying, improving production line efficiency Compliance with UL flame retardant and environmental regulations Reworkability, facilitating maintenance and quality control For different BMS structural designs and process requirements, the following various silicone conformal coatings can provide differentiated solutions.
