resin not hardening on glass?

[luisdeleon]

i used epoxy resin to do some small paches in the tray. mixed the hardener then did three to one like it says to do then applied it to 170z biax. well it's been 2hrs and the cloth still seem wet, but the left over in the cup is hard, anyone know why? well we'll se what happened in the morning

takes longer in thin coats.normal.

Left over mix in you cup will always harden up much faster from more heat that it self generates.
Epoxy resins are mostly slow cure verses polyester resins.
You'll be good, just be patient.

What brand of epoxy resin did you use? Some cure faster than others...
What did the instructions say as far as cure times?

try hitting it with a heat gun or leave it in the sun.. i had the same problem with some of the slow curing epoxi and i found if you let it sit in the cut a couple minutes before you apply it seems to cure faster.. hope it turns out man

over large enough areas, sometimes it will fracture the resin if it's cured too quickly.
