Hi Folks,
I am a new member and live in the USA. I have a problem with my resin mixture going off too soon. I bought (medium) speed resin. It is supposed to have about 25-30 min pot life at 80deg. I live in South Carolina, and 80deg is pretty cool this time of year! The temp is expected to get to close to a 100deg this weekend, just as I plan on doing a lamination project. My question is how can I slowdown the reaction of the resin? I will be working outside, so no A/C to help. Would placing the resin in a fridge before mixing help? I know I can't reduce the hardener ratio to slow it down. Any ideas?

Hi Gary,



Dealing with a thermal runaway: if you notice signs of a runaway (high temperatures in the bucket) do not attempt to cool the resin, it will defiantly be beyond saving. Take the bucket into a spacious and well ventilated area (outside is ideal) leave the reaction to take place watching that it does not run out of control, do not use water to cool the reaction, this can lead to violent boiling and spitting. In the unlikely even that the resin ignites, a fire blanket is the best way to manage the flame until emergency services arrive CO2, Foam, Chemical powders or sand extinguishing materials are also appropriate, only use water with extreme caution.

After completing a project any spare resin in the bucket should not be left unattended, it should be divided into smaller quantities and placed in a well ventilated area away from any combustible materials.


I found this out the hard way.... the spits hurt too...
