3M™ Impact Resistant Structural Adhesive (Irsa), 200 Ml, Pn07333

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

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.
