Not sure why some guys have given this bad reviews. Mine says right on the package... "Good up to 600 degrees". Seems very adhesive and is working well. Will update if I have any problems.

Worked for me
Used this to close the seams of foil covered fire proof insulation for a paint cure oven I am building. What taken it up to 300F with no issues.

Brought this to reattach the chimney piping inside the house at the back of our pellet stove. We had taken it apart to clean it all out. Joined the parts with some ultra copper, wrapped this around it to seal it, sprayed it black with rust oleum spray paint and we were back in business.

Does not work for wood burning chimney flues
did not work. I used it on a flue that I know doesn't get very hot (300°F Max) and it lost it adhesiveness after two uses. Save your money

Used this to seal the connections on my furnace/ water heater exhaust pipe. Strong adhesive and pliable.

Terrible time and complete waste of money
I wish these rating could let us rate it down to zero stars. Therefore I'll leave it at one star. But this item was the worst! Complete waste of money and time! It didn't stick and if it did, it wasn't for long! Hope you other can read this feedback and save your money instead.
