Curing Oven

[Shredd]

Agreed on the hot box...  I have three for different uses...

Good information there Shredd

Yeah that was a great promo video for Instron HV3s.

The epoxy I use will cure at any temp, but it attains max heat deflection when cured for 1hr@200deg
No hurry, just optimizing.

Flem, is that max deflection for system 3? I would be interested in reviewing the spec you are reading from.

Does this claim seem to indicate a heat treat will improve final stiffness irreguardless of cure time?

[Flem]

Thats for Smooth-On Epoximite. Not sure about the specs for any System Three epoxy's.
It's a general rule that an epoxy will achieve its maximum potential for desirable properties, including heat deflection, glass transition and molecular cross linking (strength)with the highest temp the components were formulated to cure at.

Ah, epoximite. I have never used it. guess I was seeing the clear coat you posted a pic of a while back.  (I use it quite a bit), and though have not researched lately, can only recall time and temp relating to the speed of cure, but not the ultimate strength neccesarily.
thanks

Huh
