## Description

G/FLEX EPOXY QT KIT

Review: Best adhesive I've ever used - This is the strongest adhesive I've found for most substrates (the exception being low surface energy plastics). With good surface preparation, I've had excellent results on aluminum, steel, stainless steel, carbon fiber, fiberglass, wood, and many plastics. I did some tests against 3M DP420, the gold standard of toughened epoxies, and this had better shear strength (despite being much less expensive). I've tried acrylic, urethane, and CA adhesives; none matched the strength and toughness of this. This is NOT a quick-dry epoxy. It doesn't even start to harden for a few hours. I always let it dry overnight before using what I've glued with it. It seems to reach almost full strength about as fast as 30-minute epoxies, but it has a much longer working time. Ideally, plan a day ahead. It's a little harder to use than dual-syringe epoxies, of course. If measuring volume is too difficult (say you only need a small amount), you can always weigh the components. The resin is much heavier (about 1.2X), so be sure to account for that. For example, tare your scale, add 2g of hardener, and then add 2.4g of resin.
Review: Best on the market - This is the best product on the market for knife makers epoxy. It holds your knife together. It is really the best. Step up your knife building game and get some G-Flex

### ⭐⭐⭐⭐⭐ The Best. Totally worth the money.
*by N***Y on June 23, 2024*

It's the easiest two part high tensile epoxy I've used. Mixes to a honey-like texture and flow. Gives you a solid 35 minute work time, probably longer in cooler climates. I used it to install two 40" (4" x 2") kevlar felt canoe skid plates. Used about 100 grams (50 gr of each) per skid. Lots more product still in the bottles. Wets the fabric thoroughly, smoothes out nicely. Cured in 60 minutes in the local 108 degree heat. Sands easily. Do yourself a favor.
