One-day (24 hrs) curing process can be accelerated with heat.
Ideal for either welding or riveting bonding within working time
Adheres to a wide variety of properly-prepared steel and aluminium substrates
Colored formula dispenses silver before turning purple to indicate proper curing
Offers an excellent shelf life whether opened or unopened, helping to reduce unused product replacement costs.
3M™ Impact Resistant Structural Adhesive (IRSA) is formulated for true automotive OEM-specified structural bonding applications, excellent for collision energy absorption in steel structures and advanced lightweight aluminium 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.
