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.
