Overview: The parameters tested in this study that relate to the stability are the stability/gel time at and below 90°F (32°C). The installers want the longest stability possible so they have a safety factor in how much time they have to get the material in the pipe. They also want a short "cooking" cycle that allows them to manufacture a quality liner in the shortest time once it's in the host pipe. The third important parameter is to get enough heat generated during the cooking step to drive the resin cure to an acceptable level but not hot enough to distort, crack or cause excessive shrinkage in the liner.
