Tunze Epoxy

[JSR]

I have the Tunze 2 part epoxy (dental type)

Initially tiall it worked very well, hardened quick, much easier to use etc
Lately it always seems to stay soft—-even after prolonged times in tank.
I use a 1:1 ratio white:purple. Ive tries different ratios w/out success.

Any ideas/tips?
Does it loose efficacy after several months?

It is possible if it is fairly old, it has chemically broken down and would no longer work, but the most common cause of it failing to set up is damage from temperature extremes, if it is stored somewhere where it got very hot or cold, this will damage the chemical so it no longer sets up.
