A Structural Adhesive for Automotive Substrates
Engineered to withstand much higher impact vs. traditional bonding adhesives, 3M™ Impact Resistant Structural Adhesive (IRSA) is excellent for true OEM specified automotive structural applications. It adheres to properly prepared automotive substrates including mild steel, high strength steel and automotive aluminum alloys – vital as OEMs strive to achieve high strength in increasingly lightweight structures. 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 – as long one hour – and cures rapidly with heat (30 minutes at 80ºC/175ºF). Adhesive applies in a silver color and changes to purple as it cures, indicating when the process has begun.
Impact Resistance and More
3Mâ„¢ 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. Its corrosion inhibiting formula delivers lifetime corrosion protection. The cured adhesive can also help decrease NVH in the vehicle.
3Mâ„¢ Impact Resistant Structural Adhesive is available in 200 mL cartridges for smaller jobs, and in 450 mL cartridges for use with the 3Mâ„¢ Dynamic Mixing System.
About the 3Mâ„¢ Dynamic Mixing System
With the Dynamic Mixing System (DMS), 3M has created a method for mixing adhesives, sealers and fillers that saves time and helps ensure the proper mixing of two part for
