Simplicity in epoxy adhesive use has finally arrived! Just drop System Three's new cartridge into a standard size caulking gun, add a mixer tip and squeeze and apply. What could be easier? Only need a little bit and don't want to use a tip? Then squeeze out some into a cup, mix and apply. In either case the cartridge properly measures the resin and hardener and can never get the ratio wrong. After you're done put the cap back on and the cartridge is ready to go whenever you next need it.

T-88 Wonderful adhesive but not in uTAH
I have used T-88 in bottles for several years and it is a great adhesive. T-88 in a u-TAH cartridge is not so great. There is no dye to verify the feed ratio is correct. The resin was not dispensed in a proper ratio and did not cure. I was fortunately able to pull apart the pieces.System Three makes another product, Gel Magic in the u-TAH cartridge. Gel Magic has a dye confirmation of ratio and mix being fed is correct. Gel Magic in the u-TAH cartridge is a good product. I would only suggest T-88 in bottles and mixing yourself until System Three corrects this issue with T-88 in a u-TAH cartridge.Product usage details for someone who is interested. I cleared the ports and fed a mix prior to using the mixing tip. The mix did not seem correct. I took another cartridge (new) and did the same thing. I had used the product once previously and it seemed to work well. This experience has me going back to bottles. The cartridges were in my workshop that was in the mid 40F overnight. I was using the cartridges in the upper 60F at 3PM.
T-88 is Strong Stuff!
I used this to glue up what I felt wer the most critical joints when building a Bolger Bobcat catboat. The joints came out strong and none have failed. It's fairly thick when mixed, like a warm light molasses. But when it's hot out it thins and requires a thickening agent to stay in place. When gluing up ..don't squeeze the joint so hard all the epoxy ooozes out. That's not the way to do it! Some epoxy must be left behind in the joint. Does not sand well at all. Tends to get gummy. Convenient packaging. Like the tubes. Be sure to mix properly. By VOLUME is 1:1. By WEIGHT it is 1:.83. That's important for maximum strength.Get a small quantity and make some tests. Just be sure all joints are clean and free of dust and oils. Try varying amounts of clamp pressure and check the results before you start an important project.I really like System Three "Gel Magic" too. Slightly more than T-88. It can be shaped and is sandable. Depends on what you are doing.
