System Three T-88 Epoxy Adhesive u-TAH Cartridge, 8.4 oz a simple and convenient solution for your adhesive needs. Designed in an easy-to-use u-TAH™ Cartridge format, it fits ly into a conventional caulking gun, allowing you to add a Turbo Mixing Tip (#52886), squeeze, and apply with ease. If you only require a small amount and prefer not to use a mixing tip, you can squeeze the resin and hardener into a cup, mix, and apply. The cartridge ensures the resin and hardener are measured accurately every time, eliminating any chance of mixing errors. After use, simply cap the tube to keep it ready for your next project. The cartridge features two chambers arranged one behind the other, and it is considered empty when the back plunger reaches the middle. Please note that mixing tips are sold separately.
