Product Introduction
3M™ Structural Adhesive SA9860 is a two-part, room-temperature-curing, low-density automotive structural adhesive designed to provide an impact-resistant and fast-curing bond without the use of ovens. This solution allows the use of materials such as composites, which are typically sensitive to higher temperatures, to enable lightweighting of the structure and help increase design flexibility.
This adhesive provides reliable bonding under various environmental conditions. It forms a robust, structural joint and delivers high bond strength with cohesive failure mode on e-coated and passivated aluminum. It also exhibits excellent mechanical performance and long-term durability across a wide temperature range, maintaining structural strength under high loads.
Designed for manufacturing efficiency, 3M™ Structural Adhesive SA9860 forms high-impact-resistant bonds even at room temperature, eliminating the need for oven curing and induction processing. This helps reduce energy consumption and production costs. It allows separate storage of epoxy and curing agent, extending shelf life, while its room-temperature strength build-up enhances productivity. Easy application with conventional dispensing and metering systems makes it suitable for automated production environments.
Its lightweighting benefits include reducing the number of mechanical fasteners required, compatibility with multiple substrate materials, and contributing to part weight reduction due to its low density.
Common automotive applications include chassis, battery boxes, battery composite housings, and EV batteries, supporting a wide range of structural bonding needs.
