3M™ Impact Resistant Structural Adhesive (IRSA) is formulated for true automotive OEM-specified structural bonding applications, excellent for collision absorption in steel structures and advanced lightweight aluminum alloys. This two-part epoxy adhesive delivers extended worktimes – up to 1 hour – and can be rapidly heat-cured. The adhesive changes from silver to purple as the adhesive cures.

Engineered to withstand higher impact vs. traditional bonding adhesives, 3M™ Impact Resistant Structural Adhesive (IRSA) is excellent for OEM-specified automotive structural applications. It adheres to properly prepared automotive substrates including mild steel, high-strength steel and aluminium; vital as OEMs strive to achieve high strength in increasingly lightweight structures. This two-part epoxy adhesive is recommended for all weld-bonded and rivet-bonded joints when specified by an OEM. It provides an extended work time - up to one hour - and cures rapidly with heat (30 minutes at 80° C). Adhesive applies in a silver color and changes to purple as it cures, indicating when the curing process has begun. 3M™ IRSA is designed to absorb collision energy forces and delivers increased torsional rigidity for OEM-specified automotive structures. It allows for spot-welding (form squeeze-type) in an uncured state, typically up to three hours after application. Properly applied adhesive will seal joints completely, and perform when exposed to very hot and cold temperatures. 3M™ Impact Resistant Structural Adhesive is available in 200 ml cartridges.
