Linda, I’m not aware of any epoxies that are anywhere near as thin as
Most seem fairly similar, though note that as they sit on a shelf and
get older, they seem to get thicker too. So fresher may be better.
But on a more important note, you should be aware that the quick
setting epoxies generally don’t last as long as theslower setting
ones. Water resistance over time, in particular, is poorer, and for
jewelry, exposed to perspiration and more, this is anissue.
I’d suggest the Epoxy 330 (clear color) or Epoxy 220 (amber color, a
bit stronger) brands. These, sold through jewelry and lapidary
suppliers, are especially formulated for best performance in jewelry
type uses (bonding to stone, metals, and more). They are generally
slow setting, giving you about an hour of good working time when
mixed, and fully setting overnight. But here’s the cool part.
If you’re in a hurry, after it’s applied, put your piece under a heat
lamp. That means an ordinary incandescent light bulb (60watts is more
than enough), placed very close to the bulb. There, it will get
almost too warm to touch. For organics that might not like that heat,
back off a little as needed. But with that gentle heating, these
epoxies will set up to a softish rubbery state (you cannow handle it,
no longer sticky, etc) in 5 to 10 minutes, and in 15, after cooling
down again, are fully cured and set up, though absolute full strength
still takes a bit more time (the five minute types also don’t
generally reach full strength for a number of hoursor overnight). You
get the advantages of the stronger, more waterproof slow setting
epoxies, with the ability to give you the fast cure times of the
quick setting types when you need that.
