In-House Etching Chemistry

Known for providing high quality etch services for more than 40 years, Porter Process is introducing a specially formulated compound that permits the convenience of smallbatch etching in-house.

Prime-Etch™ sodium naphthalene compound attacks the surface layer of most fluorinated polymers (PTFE, FEP, PFA, etc), stripping away fluorine to allow for the replacement of more bondable molecules that promote adhesion. Since only the surface is modified, other properties remain largely unaffected. The result is a strong, durable, long lasting etched surface. Prime-Etch can be used at room temperature and rinses clean, without leaving behind any residue. It can be purchased in quantities as small as one pint.

Porter Process is an ISO 9001: 2000 certified company, they offer fast, expert surface preparation services, creating the conditions needed for strong, uniform lamination. The company’s process can treat one or more surfaces - including selective spot etching - on continuous roll films, flat sheet or the compound contours of three-dimensional parts.
