On the little manual that came with my overture tpu, it says that you should dry it at 70 degrees. I just want to confirm that the glue will hold up at that temp.
I have had issues with another brand where the spools fell apart when I dried them at around 60 degrees, so I just want to make sure.

I've never heard of a spool having trouble at those temperatures so that's surprising. If it's what the manufacturer says to do, then go for it. If it backfires, contact support - you were just following their instructions.

I've never had a problem with drying Overture spools before. I concur that you should be able to follow the manufacturer recommendation.

My dryer only goes to 65 but that's what I dry my overture petg spools at and I haven't had any issues
