Epoxy after PVC gluing?

My next project requires me to sleeve a PVC pipe inside a length of square PVC structural tubing.

For the initial connection, I used medium thickness PVC solvent to bond the pipe to the square tube at all four lines of contact. I did this about 3 hours ago.

The next step requires that I fill in the corners with epoxy to form a solid piece. My concern was that the vapors still coming from the PVC solvent might interfere with the epoxy curing process. The main ingredient in PVC solvent is acetone, and I've read that acetone can break down epoxy resin.

Any opinions on whether I should proceed with injecting the epoxy now or wait a while first?

Acetone is highly volatile, I doubt that after 3 hours at room temperature there are any significant fumes left.

It still smells rather strong. You wouldn't worry about that?

Unless you actually poured acetone into the resin mixture, not at all.

I'll start then. Thanks for the help.
