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. 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 80°C/175°F). Adhesive applies in a silver color and changes to purple as it cures, indicating when the process has begun. Impact Resistance and More 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. Its corrosion inhibiting formula delivers lifetime corrosion protection. The cured adhesive can also help decrease NVH (PDF, 325.12 Kb) in the vehicle. 3M Impact Resistant Structural Adhesive is available in 200 mL cartridges for smaller jobs, and in 450 mL cartridges for use with the 3M Dynamic Mixing System. About the 3M 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 formulas every time. The system includes pre-loaded DMS cartridges and a series of DMS mixing nozzles, and works with a standard pneumatic applicator. Instead of premeasuring and premixing two-part products, technicians dispense the perfect amount of material, directly to the job, at the touch of a trigger. This eliminates the messy mixing process, reduces material waste and cleanup time, and helps ensure the quality and performance of finished work. 3M Impact Resistant Structural Adhesive in 450 mL cartridges is ready to use with a purple 3M DMS Mixing Nozzle, PN 55847. 3M recommends dispensing the adhesive with the pneumatic 3M Dynamic Mixing Gun, PN 05846. Better Science for Better Adhesion from 3M Since 1925 when one of 3M lab assistants invented masking tape, 3M has been applying science to life —developing adhesive products and technologies that help individual businesses and entire industries. 3M Impact Resistant Structural Adhesive (IRSA) represents these decades of knowledge. And, with its formulation for long-term strength, torsional rigidity and corrosion protection even when used in lightweight aluminum alloy structures, it is very simply the right product at the right time for automotive collision repair.

Trusted 3M Impact Adhesive

The 3M Impact Resistant Structural Adhesive 07333 offers reliable bonding designed for automotive use. This 200 mL cartridge formula is engineered to meet OEM specifications, ensuring strong and durable adhesion for structural repairs.

Its impact-resistant properties make it ideal for collision absorption in steel and aluminum parts. The 6/case pack size provides enough material for multiple jobs, making it a practical choice for repair shops.

Visible Cure Color Change

This adhesive features a unique color change from silver to purple during curing, so you can easily see when the bond is properly set. This visual indicator helps technicians confirm the adhesive is curing correctly without guesswork.

The 200 mL cartridge format works with the 3M Dynamic Mixing System, allowing precise dispensing and mixing. This ensures consistent application and reduces waste during automotive structural bonding.

Long Shelf Life Benefits

3M’s structural adhesive offers an excellent shelf life whether the cartridge is opened or unopened. This helps reduce costs by minimizing unused product replacement and ensures the adhesive is ready when needed.

The 6/case packaging supports efficient inventory management for busy shops. Having multiple cartridges on hand means you can tackle several repairs without delay or frequent reordering.

Heat Accelerated Cure Time

The adhesive cures in 24 hours under normal conditions but can be accelerated with heat to cure in just 30 minutes at 80°C (175°F). This feature speeds up repair times and increases productivity in automotive shops.

Its extended work time of up to one hour allows for precise positioning before curing begins. This flexibility is especially useful when bonding steel and aluminum substrates in complex assemblies.

Corrosion Protection Warranty

3M Impact Resistant Structural Adhesive provides lasting corrosion protection backed by a lifetime warranty. This ensures bonded joints remain strong and resistant to environmental damage over time.

Ideal for steel and aluminum automotive parts, the adhesive also improves torsional rigidity and reduces noise, vibration, and harshness. The 200 mL cartridge size fits smaller jobs, while the 6/case pack supports larger workloads.
