The pot life given for the resin is the amount of time it takes for the resin to double in viscosity. Additionally, the work life is the amount of time that the resin remains workable and spreadable, after which the curing time is the time required for it to fully solidify.
The current resin that is to be used is the West System 105 Epoxy Resin (http://www.westsystem.com/wp-content/uploads/User-Manual-2015.pdf). It has a viscosity of 1000 centipoise, very thick for the vacuum infusion process. However this can be compensated for by the resin hardener used. The most likely hardener to be used is the West System 209 Extra-Slow Cure Hardener
