*Pot life is defined as the amount of time it takes for an initial mixed viscosity to double, or quadruple for lower viscosity products (<1000 cP). Timing starts from the moment the product is mixed, and is measured at room temperature. Working time is the amount of time an epoxy remains low enough in viscosity that it can still be easily applied to a part or substrate in a particular application. For that reason, working life can vary from application to application, and even by the application method of the epoxy, so there is no uniform method for quantifying this property. This value should be viewed as an estimation.
