only 60 degrees ..    I've used it a lot, and postcured parts in "putty" moulds up to 100 deg ... Never gave it a second thought--- its Epoxy, most epoxies easily handles 100 degrees..

.. OK ... 120 degree or more Prepreg ... probably not ... but my experience tells me thet the putty does not distort noticably at 100 .. for small thick moulds...

Do not adjust our mind, theres a fault in reality :-)

The putty is only rated to 60C so you are highly limited in what you can do.  You could do a small postcure upto 60C to allow you to cure your parts at a slightly elevated temperature but the putty is not designed for out of autoclave pre-pregs.

Hi there, I couldnt find any info on the TDS and the tech questions about the epocy putty.

Im going to make a couple of car mirror moulds as they are nice and small, my main question is does the putty need to be post cured at all? and if so how much?
The other question is what temperature can they go to, can a low temp cure prepreg be used in them?

Thanks
