3M Impact Resistant Structural Adhesive (IRSA), 200 ml, PN07333

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.
