Hi all, I was doing an epoxy infusion in a cooler garage so I was heating up the mold and part A of the resin in a little heat box with a space heater. Both were around 50C which I had done before on a previous part. This part used more resin (880g total) and it just fit in my container. I felt there wasn’t enough room for the degassing froth so I separated it into two containers. The first degassed fine and when I put the second in the bubbles were quite slow as if it were thicker. About 4min in it started to bubble but it looked like it broke through a hard layer on top and then it started to smoke. I checked my first batch and it was also smoking/starting to cure in the container. On the previous parts (660g total resin) it took a good 45-50min to thicken up and this one was only about 18-20min in from being mixed.
Did I heat the resin too much before mixing?
Should I only heat the mold and not the resin for an infusion? I can keep the resin in the house at room temp until I mix it up if that would work better.
I’m a bit confused as I was under the impression that heat wouldn’t speed the cure on an epoxy. I can’t afford to lose this part if I try again and that happens during the infusion.
Any help or comments would be greatly appreciated. Luckily I get a second try.
