Shelf life of PVC edgeband?10/17
I've been discussing PVC (0.5mm) edgeband shelf life with a handful of folks, including the tech at Stiles.
The consensus is that there is a primer on the back of most that can age, and once it's hit a few years old, it can make an unreliable bond.
I've noticed this myself when "using up old junk" on misc stuff. I've seen it peel off a lot easier than fresher stuff.
Since i just pitched some edgeband that turned out to be 11 years old, I'm wondering what you all consider to be "too old to be reliable".
I read the Dolkein pdf that discussed storage and they claimed it was basically impervious as long as kept in a climate controlled environment. We actually do that, we have a storage room in our office we keep them all in.
My take is forever, where does the so called primer go? evaporate? Maybe if you store it in the yard it may be a concern, but in a controlled environment the stuff will be fine for a lifetime or two.
We had an issue a few months NYU’s back with 1mm pvc that was breaking on the end trim played with binder for half day trying to figure out. We swapped out to another role and problem went away. First role was 18 months since manufacture date other role was new. Draw you own conclusions
I have never had a problem, I dug out a partial role that I used ten years ago to match a job and it worked like a charm. However what Derrek said would be more of a concern than the actual adhesion, if the material is brittle it may crack and check? I guess I may have been lucky, the one good thing is the stuff is super cheap, so just buy a new role if your concerned.
