Thixo Flex is a thickened epoxy adhesive that forms flexible, high-strength bonds on wood (even teak and other oily woods), fiberglass, metals, glass, & some plastics. Upon cure, it creates permanent, structural bonds that absorb shocks, stresses, & vibration.
This cartridge-dispensed non-sagging epoxy is great for building or restoring wooden boats prone to flexing during use, and movement from weather-related expansion & contraction. Thixo Flex can be applied to dry or damp surfaces in temperatures as low as 40°F. You'll appreciate the long working time & easy cleanup.
Handy cartridges fit standard caulk guns. Use the included mixing tip to measure, mix, & dispense a bead that's the precise 1:1 mix of resin and hardener to get a proper cure each time. No need to measure, mix, or worry.
One 250ml cartridge includes 2 static mixing tips.

Forms permanent, flexible bonds on fiberglass, glass, metal, plastic, and wood, including hardwoods that typically are a challenge to bond because of their natural oils.
Waterproof bonds hold firmly when subjected to contraction, expansion, shock, & vibration.
Convenient cartridge fits into a standard caulk gun.
Static mixing tip fits firmly onto cartridge to easily mix, measure, and dispense the precise ratio of resin and hardener for you.
Apply to dry or damp surfaces.
Long working time of 75 minutes is ideal for larger projects that require extensive gluing.
Can be used in temperatures as cool as 40°F.
Buff-colored cured epoxy can be sanded and painted.
Compare to two-part West System G/Flex 655. Thixo Flex is a better value, and is easier to use because the resin and hardener are contained inside a single cartridge that fits into a standard caulking gun (sold separately). There's no measuring, mixing, or mess because the included static mixing tip measures, mixes, and dispenses the exact ratio automatically.
In addition, Thixo Flex has higher flex tolerances and lasts longer than flexible, one-part urethane adhesives and sealants.
Application Notes: Store Thixo Flex cartridges at room temperature (60-90°F) before use. Apply when the temperature of the ambient air and substrate is 40°F or warmer. When finished, leave the static mixing tip on the tube to cure. For the next application, simply remove and replace the tip. Do not attempt to clean the tips.
Note: For use in manual caulking guns only.

Number Of Parts:
I have an old wooden Lightning sailboat with a planked bottom. I need to re-caulk the plank seams to make it water tight but also need to allow room for the wood to swell and expand and contract with temperature. Will Thixo Flex work for the application and allow for enough flexibility so the planks do not buckle as they swell when in the water?
I wouldn't recommend an epoxy even thixo flex because they won't flex enough. I would recommend Sikaflex 291 caulking.
what is the difference between Thixo Flex and Thixo 2:1? Installing a bulkhead and not sure which is best to use?
Thixo Flex is just that, flexible, and will move with the boat. Not familiar with Thixo 2:1, but if it's the regular Thixo, it may crack as the boat itself flexes.Tip: If you don't use the full amount, keep the original tip and nut, even when you've used up the nozzles. You can replace the originals and keep the tube for small jobs and touch ups. It will last for months.
Thixo Flex is a thickened flexible epoxy that is more flexible than regular epoxy. Thixo 2:1 is our regular thickened epoxy.

can total boat thixo flex epoxy be used to wet out fiberglass cloth?
Not be best application, it is thick and will not penetrate the fiberglass cloth properly. If you want a product in a tube, use the Thixo LV Low Viscosity.

Will this adhere to the cut edge of plexiglass or a smooth aluminum surface ? I need a strong permanent bond. And is it flexible like rubber ?
It will adhere to properly prepared surfaces of plexiglass(sanded and cleaned) and aluminum cleaned with our Aluminum Etch Wash. It is a hard epoxy but a little more flexible than standard epoxy. Not like rubber at all.

I have an Avon hapolan dinghy that the wooden transom has separated from the hapolan.(do to a crash). I Totalboat Thixo expoxy a good adhesive to use? If not any suggestions.Thanks
Not sure if this would work as well as Marine-Tex FlexSet which lists:FlexSet bonds to PVC, fiberglass, polyurethane, wood, Hypalon, ceramic, rubber, glass, acrylic, steel, polycarbonate, aluminum and Lexan.

Looks good but too soon to tell if it will perform
I used this to fill stress cracks in the glass on the interior deck at the bulwark joint, stem to stern on an 18' dory. it came out of the tube VERY slowly, though I probably need a more powerful caulking gun and it was cold when I applied it.
I would buy this product again, very pleased
I used this product to repair some cracks in the console of my pontoon boat. After opening up the cracks about 3/8 inches I applied the product using the special mixing tip and level it out with a wide craft stick. After it dried I sanded out then painted. Turned out great.
Buy a good gun to go with this.
I would recommend you purchase a good caulk gun rated for adhesive with at least a 10:1 drive/torque ratio. This stuff is thick, and even a pretty good gun from Ace Hardware wrecked my hand. I ended up getting a better gun (Albion B26) for next time (26:1). Be sure to trim the tip to the desired bead size, as without doing so is is a very small bead. There is deceptively not that much material in the tube, that would be my only complaint.
I used this on some teak furniture pieces I made because I wanted to ensure the bond would hold the oily teak parts together permanently.
worked great will buy again
I had a teak cabin door that was basically destroyed by 250 lb man and a 8 foot wave. Needless to say the door needed major reconstruction. The epoxy blended well with color agent and the door went together with plenty of work time. 2 louvers were broken dead center and when glue cured the louvers remained flexible like the others. One day later you would never know it was destroyed so badly
I would buy this product again.
I am in the process to replace some old and worn-down teak decking with Alaskan straight grain yellow cedar 1/2" thick with 1/4" caulked grooves teak caulking).It is extremely hard to get the Thixoflex out of the tube with the very best manual causing gun.I even bought a pneumatic gun etc., but that does not work, because of the way the two parts are placed inside the tube. There must be a better way!!!I don't use any screws, but only the Thixoflex which is working just fine. Just getting the 2-part material out of it's tube is very, very difficult!!

good product, sets up in low temps as instructions stated
product was used to treat the hull-keel joint, and because it is a more flexable epoxy, it is perfect for this area.
I am rebuilding the transom on a Chris Craft Constellation. I have use this to fill old holes and to glue planks together to reinstall the subfloor under the teak deck. It creates a solid bond. The only real negative is that it can be REALLY hard to push through the nozzle even after warming it up and there is a lot of waste in the mixing tip. If you just need a small amount I have found it better to just squirt some out of the tube onto a mixing tray and stir it up yourself and then apply. Mix it thoroughly though. I have not had any problems with the curing or bonding doing it this way.
Easy to use
We like the product, it mixes well and in the proper amounts. We used it to attach the rail cap on our Penobscot 14 "St. Jacques" and to attach a skeg on the 1880s rowboat "Barbashela."
