If PTFE Is non-stick, how does it stick to the pan?

PTFE (polytetrafluoroethylene) is renowned for its excellent non-stick properties, but since it naturally repels adhesion, bonding it securely to a pan surface requires special techniques.

Manufacturers use a multi-step process to ensure the PTFE coating firmly adheres:

  • The pan surface is roughened or etched mechanically or chemically to create microscopic grooves.

  • A primer or bonding layer is applied to promote adhesion between the metal and the PTFE.

  • Multiple layers of PTFE are then sprayed or rolled on and cured at high temperatures to fuse the coating to the pan.

This process results in a durable, non-stick surface that resists peeling or flaking when cared for properly.

Understanding how PTFE bonds to cookware highlights the importance of following care instructions—using the right utensils, avoiding overheating, and gentle cleaning—to preserve the non-stick layer for longer-lasting performance.
