Pot life is defined as the amountof time it takes for an initial mixed viscosityto double, or quadruple for lower viscosityproducts (<1000 cPs). Timing starts from themoment the product is mixed, and is measuredat room temperature (23˚C). Variations in temperature, the amount of epoxy mixed, and when the epoxy is applied can affect curing time drastically.
Working life or gel time is the generally accepted time in which you need to have all of your movement done and parts in position. There is no universally accepted measure of working time. Even if there was, it is still highly dependent on site conditions like external temperature, how long it's in the pot, size of the pot, etc. For example, if you lower the ambient temperature from 80 degrees to 65 degrees, most epoxies will take twice as long to cure.
The processing parameters I settled on were: 1) control the temperature in the room to keep it at 70 degrees 2) Only work with the epoxy for the listed pot life 3) If mixing more than 75g of epoxy, apply it all in the first few minutes after mixing to prevent premature cook off and 4) Cure for 2 times the listed set time.
Those rules pretty much cover almost all my basis. Eventually I am going to build an oven to cure at elevated temperatures to better hone in the system. If your re-positioning because the epoxy is running, try a thixotropic agent like fumed silica to firm it up while at rest.
