Dear users,
I'm currently working with multiple epoxy resins, but after curing on ambient temperature, i can't determine which one is A-stage and which one is B-stage, which is very important.
The B-stage epoxy only partially cures and this one needs to be cured a second time to gain full conversion.
Now my question is, how do i determine which one is the B-stage? i have a lot of material all over the place and it isn't really pointing itself out.
Thanks in advance,
Frenk

The problem is the "A stage" etc method of describing cure is different for each resin and also confusingly it is referred to differently in some circles to mean a different level of cure to what is described here and elsewhere.
Often it can be better to use more descriptive phrases such as "tacky but firm" "demouldable" "fully cured" etc as the meanings are easier to understand and explain.
