Hi.
I somehow managed to mix up my two hardener bottles, and used polyester hardener for epoxy resin. I believe it just wont work.
but how long does it take for the resin do cure without any hardener?
I don’t think is going to cure:D
Got my answer already from a friend. It will cure if its in a warm room\oven in about two weeks, but there is a chance that it might remain sticky.
Stick it out in the sun on a sunny day or many days…
PER has colbalt and reacts to the peroxides to generate heat for curing.
What I did in my former classroom was to use color tie wraps to id chemicials, all clear:
Lime green = Sheet glue / solvent
Red = acetone
blue = alcohol Iso.
Dark green = MEKP
Etc…
