TEMPERATURE MANAGEMENTBEYOND THE EXPECTEDBATTERY THERMALINTERFACE MATERIALSTHERMAL CONDUCTIVEGAP FILLERSIMPROVED ASSEMBLY PROCESS WITH SikaBiresin® TC

CHARGE YOUR AMBITION WITH SIKA. Using our long-term experience in dielectric
potting, Sika has developed thermal interface materials for battery systems, that
ensure optimal heat transfer in battery packs and modules.

The SikaBiresin® TC series are used for Thermal
Conductive (TC) gap filling applications. It also serves
as a functional interface in the battery arrays andworks interactively to provide heat transfer for active
temperature control systems of the battery packs.
Products are available in both silicone and silicone-freeformulations. Performance levels are available in therange of up to 3.0 W/mK, products are room temperature cured and glycol resistant, and meet the UL94-V0
standard.
“On-demand” adjustable curing processes add value
to conventional assembly processes. Additionally,
thanks to low compression force and viscosity,
SikaBiresin® TC gap allowing for easy assembly
combining with low abrasion. Moderate adhesion
strength also allows for disassembly and serviceability.

Thermal conductive adhesives (TCA) offer added benefits formanufacturers seeking to meet future requirements. As manufacturers transition to Cell-to-Packdesigns in order to improve the stiffness and torsional characteristics of the vehicle’s bodystructure, bonding with heat-conductive adhesives will become more common.

Sika’s high-performance bonding solutions offer
thermal-conductivity and electrical isolation characteristics for packing the battery cells inside the arraymodules.
Sika TCA offers thermal conductivity performancefrom 0.8-2.0 W/m.K as well as high strength andexcellent adhesion; all without surface pre-treatmentof metals. All products meet the UL94-V0 standard
and ease of use in the application, whether applied
manually or with standard automated equipment.
