Surface Energy Follow-Up
"I read a post you had on here a while back. You talked about surface energy and what kinds of adhesives work the best with different substrates. I am looking for something that will need to adhere to polyester. Does polyester have high surface energy? Where can I find a list of different substrates and their surface energies?"
Polyester has a surface energy between 42 and 50 dynes per centimeter. This is in the between high surface energy and medium surface energy.
There are many places you can go to find simple charts that give you an idea of the surface energies of some basic substrates. 3M has a web page on their Corporate website that goes through surface energy and has various charts on different substrates.
