3M™ Impact Resistant Structural Adhesive is a two-part epoxy adhesive which provides an extended work time, but can be rapidly cured with heat. 3M Impact Resistant Structural Adhesive has excellent adhesion to a wide variety of properly prepared automotive substrates including steel and aluminum.

This adhesive is intended for true structural bonding applications when specified by automotive OEMs, and is recommended for all weld-bonded and rivet-bonded joints.

The 3M Impact Resistant Structural Adhesive also has a unique feature indicating when the curing process has begun through color change technology. Adhesive bead starts silver in color and changes to purple once curing is underway. Cured product is purple to indicate proper mixing and complete cure.
