Bonding PTFE to EPDM
Bonding PTFE to EPDM
(OP)
I am designing a product which will be using a diaphragm. It needs to be PTFE coated EPDM. The supplier sent back samples bonded with an acrylic-based double-coated film. These diaphragms peeled right apart. I believe there is a better way to bond PTFE to EPDM. I have heard that the best way is to burnish the PTFE surface with a primer and then bond using a cyanoacryate gel. But this is just one idea. What do ya'll think? And can you recommend some product?

You have to work with the adhesive suppliers to find out which adhesive will work the best with each system.

Why do you need Teflon?
