Electronic control
New energy vehicle electronic controls are iterating in the direction of high voltage, high power integration, small size and lightweight, and have long been faced with severe vehicle working conditions such as high temperature, strong vibration, and alternating temperature and humidity. MCOTI adhesive can simultaneously achieve insulation and heat conduction, sealing and vibration damping, and bonding of dissimilar materials. It adapts to the trend of electronic control upgrades and is a key supporting material to ensure the stable and safe operation of electronic control.

Thermal conductive potting glue
As the electronic and electrical architecture of new energy vehicles develops toward high integration and high power density, control modules such as DCU, ECU, OBC, and DC/DC have long faced complex working conditions such as high temperature, vibration, heat and humidity, and hot and cold cycles, which have put forward higher requirements for the heat dissipation efficiency and reliability of electronic components. Thermal conductive silicone potting glue can be used to encapsulate PCBs, power devices, magnetic devices, connectors, etc. in whole or in part. While providing excellent environmental protection, it can also achieve efficient heat conduction and stress buffering, improving the long-term operation reliability of the entire machine.
