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

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.

Just what I needed!
By Tom M from Florida

Verified Purchase

Have a large joint where the back roof of my boat meets the pilot house. After years of dealing with water intrusion despite seam sealant, I epoxied it. Needed something flexible and this was it.

Cleaning joint
Finished job.

Disappointing flex epoxy that sags while curing.
By JC from Westport Point, MA

Verified Purchase

Unlike other brands, such as Petit Flexpoxy, Thixo sags while curing. I'm using this to glue wooden boat structures that flex. I need to cover the glue-up with wax paper to stop the sagging while it cures. A time-consuming nuisance.

Bottom Line No, I would not recommend to a friend

Good Product
By Schoonie from Beverly Hills, Florida

Verified Purchase

Works great. Plenty of time before it hardens. Be sure to waste the first 3 or 4 inches to insure you are getting a fully mixed product (note the color change when properly mixed).

Bottom Line Yes, I would recommend to a friend

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
