System Three SilverTip Gel Magic Adhesive u-TAH Cartridge

System Three's u-TAH Cartridge eliminates the need to carefully measure part A and B (resin and hardener). This dual chambered cartridge features unique mixing tips to blend resin and hardener as it's dispensed. The result is epoxy precisely where it is needed, with minimal waste.

Silvertip Gel Magic is a two-part epoxy adhesive that will not sag or run. Designed for wood and other porous materials. No more measuring fillers. Gel Magic components mix into a paste that is ready to be applied to vertical and overhead surfaces without sagging or otherwise making a mess. GelMagic can be post-cured up to 140 degrees for even greater performance.
