battery pack
New energy vehicle battery packs are developing towards high energy density, high integration and long life, which puts forward higher requirements for structural reliability, thermal management and electrical safety. MCOTI adhesives have multiple functions such as structural bonding, thermal conductive potting, sealing protection and insulation protection. They can effectively improve the overall strength and sealing performance of the battery pack, optimize heat conduction paths, alleviate thermal stress, and ensure the safe and stable operation of the battery system under high and low temperatures, vibration and complex working conditions.

Thermal conductive caulk
There are common assembly tolerances and air gaps between cells, modules, liquid cooling plates and casings, which affect heat transfer efficiency. Thermal conductive gap filler (Gap Filler), with its excellent thermal conductivity and flexible compression characteristics, can fully fill irregular gaps, establish a stable and efficient heat conduction path, and quickly transfer the heat generated by the battery core and key components to the liquid cooling plate or heat dissipation structure, effectively reducing the battery operating temperature and improving temperature consistency, and improving the reliability, safety and service life of the battery pack.

Flexible paste material that can fill assembly tolerances and complex gaps

After curing, a stable thermal conductive interface is formed to achieve efficient heat conduction.

Provides a variety of thermal conductivity and hardness specifications to meet different design needs

Product advantages

High thermal conductivity: 3.2–12.0 W/m·K, meeting different thermal management needs;

The colloid has low hardness, effectively absorbs assembly tolerances and relieves thermal stress;

Two-component is suitable for automated dispensing, with a fixed mixing ratio, stable process and high efficiency;

The highest dielectric strength is >8 kV/mm, meeting the insulation requirements of high-voltage battery packs;

It is resistant to high and low temperatures, resistant to aging, and maintains thermal conductivity and sealing properties for a long time.
