Extending epoxy pot life??
"Steve" writes:
Anyone have any tips (other than using different hardener ratio's) to extend the pot life of epoxy resin. The 95degF heat is reducing my pot life from 3 hours to only 1 hour or so. Good grief, if I get 15 minutes of pot life, think it is an eternity. 1) Mix smaller batches. 2) Mix in buckets where the diameter of the bucket exceeds the depth of mixed epoxy about 6:1 (ie: 6" dia, 1" of mixed epoxy. 3) Avoid laying resin in the heat of the day and in direct sunlight. Many is the time I started laying glass at 0630, had to quit by 0930, then returned to lay glass on the opposite side of the hull around 1600 continuing until dark. 3) Work fasterG. BTW, NEVER muck with the ratios. This is epoxy, not polyester.

Extending epoxy pot life??

wrote something .......and in reply I say!: I think there is something strange if you are getting 3 hours or even 1 hour out of epoxy. 15-45 minutes is about right. What brand are you using? You should not alter mix ratios. Araldite was about as free a make as any for this, and even it had limits. People get quite anal about mixing accurately, with good reason. Anyone have any tips (other than using different hardener ratio's) to extend the pot life of epoxy resin. The 95degF heat is reducing my pot life from 3 hours to only 1 hour or so. Chilling the resin and hardener? Chilling the mixed epoxy?? Other ideas. -- Steve G 281-376-2682 Houston, Texas Remove the 'NS' from my email address to reply. ************************************************** **************************************** Huh!
