Adhesives for PTFE

How to bond PTFE?  Permabond has adhesives for PTFE.  PTFE is commonly known by the trade name Teflon® or the proper name “Polytetrafluoroethylene.” It is a notoriously difficult material to bond as it is non-stick by nature. It is often used for applications where high temperature and/or exposure to harsh chemicals will be an issue.

Adhesives for PTFE:

Structural Acrylics

Permabond structural acrylics will provide the strongest bond.  Below lap shears of PTFE bonded with Permabond TA4610 and pulled show the PTFE deforms prior to the bond.  When even more force is applied the PTFE breaks before the bond.

Prime the PTFE with Permabond POP prior to bonding for best results.

How to bond PTFE – Tips for surface preparation & bonding:

For untreated PTFE there are several options:
a) bond untreated – select Permabond TA46XX (TA4605 and TA4610) structural acrylic products, these are developed especially for low-surface energy polyolefins and PTFE.
b) prime with Permabond POP and use with cyanoacrylate adhesive only (other adhesives are not compatible with POP).
c) Use a fluorocarbon etchant such as “Tetra-Etch”, once treated this offers much greater choice of adhesive technologies used.
Corona, flame, plasma treatment and abrasion show virtually no improvement in adhesion strength.
