Traditional joining techniques in the automotive industry include welding and mechanical fasteners. However, many challenges arise when using these methods. By using structural adhesives, the need for mechanical fasteners as well as post-weld rework is eliminated. Adhesives also eliminate heat-affected zones and can double as a sealant. In traditional fastening methods, mounting lugs, screws, and rivets pierce through the aluminum battery box, which can cause a potential leak point and risks potential for outside moisture to seep into the battery pack.

The use of adhesives such as LORD® 850/25GB, can also help lightweight an assembled battery pack. Welding requires metals that are thicker—and therefore heavier—than those required for adhesive bonding. With the shift from heavy metals to alternate metals and composites, adhesives are increasing in popularity. Our presentation will cover these five reasons to use an adhesive like LORD 850/25GB instead of traditional fasteners to assembly EV battery boxes:
• Chemical Containment
• Material Strength and Integrity
• Manufacturing Efficiency and Cost
• Increased Vehicle Performance
• Health and Safety
