heating and outgassing
Posted by Jim E on Dec 31, 2006
For what it's worth, here's the procedure I follow for preventing outgassing.
Run both electric heaters full blast and watch the thermometer. When it gets near 70, or reaches a peak somwhere between 60 and 70, I turn off one heater and mix epoxy. When done epoxying, I turn the remaining heater to a low setting and go do something else for two hours. Once the epoxy has gelled, outgassing is no longer a risk, so I can bring the temp back up to put on a fill coat. I don't use a tent, but the principle of pre-heating, then allowing the temperature to gradually fall should work in a tent.
