Looking for an epoxy with a simple elevated cure

Can anyone give me some suggestions for an epoxy that fits my needs? I did some searching on here but I couldn’t come up with specific enough search terms to give me useful information.

I am looking for an epoxy system I can cure or post cure at elevated temps with a tg of 180f-200f. The post curing schedule would need to be something I could achieve without a PID system on a simple home build heating box- Meaning no complicated sweeps through a bunch of different temps.

The system 2000 from fiberglast with the 2060 hardener looks about right but I have found there are usually better or cheaper options than what they offer so I am hoping for some suggestions.

Oops. I meant for this to go in the products discussion sub-forum.

You may want to look at the Aeropoxy line of resins. The Fibreglast is just Aeropoxy that is private labelled.
BTW, When you are looking at resin data sheets and cure schedules remember the post cures listed are not necessarily the optimum schedule. The only thing being shown is for the given cure schedule the properties listed will result.

That is extremely helpful. There is a lot more information if I do searches for aeropoxy than fiberglast. Also, the gallon kit is much less expensive.

Thanks for the tip. The 2032 kit gallon kit from aeropoxy is so much cheaper.

As a follow up question, does anyone have practical experience with pr2032/ph3660 curing and post curing results?

I do, I use it regularly

AVT Composites are a vendor here and carry it. Jeremy there is of great help and can answer questions about it. They make parts from what I gather so they have personal experience with products they sell. I went with the 3665 long cure as they said its good for vacuum bagging giving you a good up to 2 hour work time. Which is much shorter with my garage temps I’m sure. I’ll post back in here with how I like it.

Btw I made parts with a low tag and was worried but after a good clear coat they’ve seen hot Texas sun and no issue yet.
