3M™ Impact Resistant Structural Adhesive 57333, 450 ml DMS Cartridge 2/Case

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.

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 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.

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.

Since 1925 when a 3M lab assistant 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.
