silmer 249b mix with the right amount of wax in around 75 degrees how long of pot life do you have to work with?
The amount of MEKP catalyst determines the pot life and cure time of working with polyester resins. Surfacing Wax is used for hotcoating and makes the resin not tacky and sandable.
At 77F 2% MEKP added to any polyester resin will provide a gel time of 10-15 minutes. Warmer temperatures or more catalyst will decrease the time, cooler temps or less catalyst will increase the time.
