I got some new cups for mixing PR (I think they were Hefty brand). Poured 12oz of resin and about 70 drops of hardener. Mixed it up. Put it in the pressure pot at -25mmHg for 5 minutes. When I took it out I noticed the walls of the cup were unusually flimsy. I figured the MEK was the culprit. Before I could get another container to pour the resin into the cup failed and this is what I got.
I used to use recycled clear plastic Starbucks cups but ran out. Is there a brand of plastic cups that you use with success?
