Rob,
I can't remember. I think it was a combination although it took
weeks, it may be that they did both and took the worst case. In any event,
after a year I'm told they're all within 5- 10%. I was happy with the 78deg
so didn't press too hard. let's see what comes of this set.
Cheers, Ferg

| Were the samples cured only at room temperature of were they subjected to
| elevated temperature cure as Europa recommends?

| Cheers,
| I had the same worries several years ago and got the same
reply.
| Nevertheless, I used the 'lighter' hardener whenever the choice was
| available. I am delighted to see that they are sticking to their guns.
| That said, I had a buddy in the business take several samples
of
| Aeropoxy, and send them to the labs in Stuttgart for formulating and
| testing. The report came back that, properly mixed, the Normal syrup and
| hardener (I don't have the numbers to hand, but they are neither fast nor
| slow hardener ones) rveal a Tg of 78.3deg C - not a bad state.
| I am now going to ask him to send later samples for the same
| purpose and if successful, will relay the results.
