Product Details

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 most 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.

Note: For use in manual caulking guns only. Do not use with pneumatic gun.

Info & Guides
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 most standard caulking guns (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: Thixo cartridges have a slightly offset nozzle that fits most, but not all, caulk guns. Caulking applicators used with Thixo need to have a hole large enough for the mixing tip; cartridges won't fit applicators with only a small hole for the nozzle. For best results, use a caulk gun with an 8 to 1 thrust ratio or higher. For use in manual caulking guns only.

Super Epoxy
By Tony C from WestPenntucky

Verified Purchase

I used it to repair cracked fiberglass. I also was able to apply it very thick on a damaged vertical surface by mixing in some flocked cotton fiber to make extra thick and apply with a putty knife. GOOD STUFF

I would buy again.
By Tom Cothern from Lynn Haven fl

Verified Purchase

First time using did not get a good mix. I followed the instructions for a 3-4 inch line of epoxy and thought that was all. When I applied it started to turn brown, as it should, about 5 more inches into the repair. It would be nice to have more mixing tubes.

Bottom Line Yes, I would recommend to a friend

Thixo Flex
By Santa Barbara classic boat restorations. from Santa Barbara, CA

I had an external crack in Gelcoat mid boat and removed a small section of the Gelcoat and fiberglass down to wood. I added a wood hardened I flex flex applied in one coat, sanded smooth. Smooth, really great product. Stuck hard to edges of Gelcoat. It didn't sag and I laid it on pretty thick.

Bottom Line Yes, I would recommend to a friend

Another Great Gun for a Great Product
By Skipper Bill from Delmar, NY

Just reattached an 18" x 4" x 3" concrete trim piece which broke off the edge of my front porch floor slab. 1. Sure glad I read the reviews which recommended an 18 to 1 ratio of dispenser handle travel to plunger travel to make it easier to squeeze out the Thixo Flex. Don't know how you could do it with the standard 8 to 1 dispenser. But found an even better dispenser from "SolidWork." It has two selectable ratios, 12 to 1 and 24 to 1. I used 24 to 1. Made the job a piece of cake. 2. "When finished, leave the static mixing tip on the tube to cure. For the next application, simply remove and replace the tip." Quoted from the ThixoFlex cartridge instructions printed on the tube.

Bottom Line Yes, I would recommend to a friend

Great
By Canoe nut from Upstate new york

Verified Purchase

Great to get "premixed" epoxy but still some waste. Great for large projects that need at least 1/2 of a tube or more. Long open time. Needs a quality caulking gun to extrude the viscous epoxy

Bottom Line Yes, I would recommend to a friend
