Chemically etched (bondable) PTFE

Overview

Etching changes only the surface layer so that standard adhesives can grip it. The face turns brown; every other property of the PTFE stays the same.

Keep etched material wrapped and out of ultraviolet light until use, as UV degrades the bondable surface.
