Hi guys, 

I made a mold with isophthalic polyester resin, I used MEKP in 1% of the weight of the resin.
After 24 hour it did not harden 100%.
Do you have any solutions to save this template? What to do ?
Grateful!

Just be very patient ... BigGrin  it will cure eventually .. but it may take a very long time-  remember that MEKP is not a "Hardener" like in epoxy, but a catalyst, or "Accelerant"
If you are in a hurry, then you will have to redo the mould.
