Any idea on the shelf life of 567 with PTFE/teflon?
I put a dab on a piece of paper overnight and it hasn't set up at all.
The shelf life for 567 is two years from date of manufacture.
Red and blue loctite expire in one year after opening the tube.
All of them are anaerobic.
According to the Loctite web site, it is thixotropic. Which I then had to look up.
"Thixotropic materials are odd solids and fluids that change their viscosity when loaded by stress by becoming less viscous. This ability is a non-Newtonian property. This means that, at rest, the material becomes more solid than it is when compressed"
So basically it cures when put under stress.
I hate leaks and have been successful avoiding them using loctite 567 and loctite 770 primer as directed.
