The only problem of adhesion I ever came across (but as you read on, you will see it wasn't after all) was stacking on top of metallics.
I was running some expensive one-off fitness suits promoting a coconut water that required many different color combinations.
Specialty Materials Thermo Flex instructions warn to not use metallics in multi color designs
I assumed that this really only meant to not stack it on top (which I was planning) since all colors use the same adhesive, and only the top material changes.
A tech there took the time to cut a design and try it both ways, wash it, and report back! Wow, I thought.
An hour later, he called back to report, that yes, I could stack silver on black, and also, damned if it didn't work the other way around as well! He thanked me for helping him learn something new!
As I said, that company is great for tech support. Siser could learn a lot!
