Bonding and Etching Process
The double-sided etched PTFE film undergoes a chemical etching process that modifies the surface at a molecular level, enabling strong adhesion to various substrates. This process involves:
- Surface Preparation: The PTFE surface is treated with a chemical etchant, removing fluorine molecules to create a reactive surface.
- Enhanced Bonding: The etched surface allows secure bonding with resins, metals, rubber, and other materials, making it ideal for composites and industrial applications.
- Preservation of Properties: Etching affects only the top few molecular layers, preserving the low friction PTFE and chemical resistant PTFE properties of the film.
For optimal bonding, we recommend storing etched films in controlled environments to maintain surface reactivity. Water contact angle measurements can be used to verify etching quality for consistent adhesion performance.
