Inserted into the back of the adhesive dual cartridge, the AT-500 dual pusher rod is used to dispense equal amounts of AT-2010 General Purpose Adhesive or AT-4020 Non-Sagging Adhesive For Plastics for manual mixing.
It is possible to use this plunger to manually dispense the AT-8040 Non-Sagging Adhesive for Metals, but the 8040 is so viscous and difficult to push that everyone uses the AT-300 Applicator Gun for this adhesive.
All the above adhesives have a 1:1 mixing ratio, and thus are dispensed in equal amounts.
This dual pusher rod cannot be used with mixing tips as it does not generate enough force to push the adhesives through the tip.
