When the best adhesive for a bonding application is a two-part formula that must be mixed before application, engineers sometimes avoid using it because they can’t be certain it will be mixed correctly. 3M Automotive has commercialized a new technologycalled adhesive taggantsthat can improve control over the mixing of two-part adhesives.

The technology--called a tagged adhesive--contains a special particle that allows the adhesive to be electronically monitored so the right amounts of resin and catalyst are combined and applied.
