Hello everyone,anybody knows if the easycompoaites very high temp epoxy can partial post cured at 60-70c?what will be the Tg?

you can find everything you need in the technical data sheet of every product on the product page  

I found the tds sheet,they say you can partial post cure the system but i ask if someone know or ever try the partial cure,i want this info cause i need the higher tg at this post cure,i cannot raise the temp because i have the pastic cores under the carbon lamination,so i m looking to find if this high temp system can achieve a better tg after post curing at 70,than other usual laminating systems

I have postcured the EC high Temp resin at 90 -100 deg on several occasions .. when left for some time (weeks) after the postcure, my samples were above 130 deg. Tg

To ENSURE any given Tg  you must ramp up to the Tg you want .... following the TDS sheet.

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

With this epoxy i have the tds so i can follow this and not try and error like the other i used!

As said a good rule of thumb is the resin will have a TG around the temperature you postcured it to, especially in the early stages since initial cure.

You will find with time, the TG will improve as some of the uncured resin naturally cures, however you are not going to achieve the full 180C Tg naturally no matter how long you leave it as there isn't enough energy at room temperature to achieve the full level of cure needed.

Hence we always recommend a full postcure to achieve the highest possible Tg and best mechanical properties.
