SAE J3178 Information Report for
battery adhesives, sealants available
In late spring 2020, SAE International released SAE
J3178 - Adhesives, Sealants, and Heat Transfer
Materials in Battery Systems: A Primer on Materials,
Applications, and End- Use Performance
Requirements. The 44-page Information Report offers
an introduction to the use of adhesives, sealants, and
heat-transfer materials (HTMs) for battery systems.
Adhesives, sealants, and HTMs play a pivotal role in
the assembly and performance of battery systems for
mobility applications. Proper selection of such
materials-from the cell to the pack level-is vital for
achieving high-throughput manufacturing and for
effectively and safely managing mechanical,
environmental, and thermal loads in the end product.
What's more, serviceability and global regulatory
requirements must be considered during the selection
process.
SAE J3178 introduces the basic concepts and
properties of these specialized materials and the roles
they serve in battery systems. Specifically, Section 4
provides a brief overview of the common chemistries
used to formulate adhesives, sealants, and HTMs for
battery systems. Relative performance characteristics
coupled with handling, environmental, and
recyclability aspects are highlighted.
Sections 5 through 7 of the report provide a deeper
review of the three types of products. Material
definitions are provided along with details of
subclasses, noteworthy formulation constituents, and
pertinent industrially accepted test methods. Section
8 is devoted to educating the reader on how the
materials are dispensed in a manufacturing setting.

Systems Adhesives, Sealants, and Heat
Transfer Materials Committee.

Tim Fornes, one of the chairs
of SAE's Battery Systems
Adhesives, Sealants, and Heat
Transfer Materials Committee,
talked with Automotive
Engineering magazine about
J3178. " I think the report does a
good job of really opening up a
lot of information that people
just don't get because of
proprietary reasons, " he said. " A
