Fluorinating - activating a plastic surface to improve paint adhesion

Fluorinating

During the fluorination of three-dimensional parts, they are exposed to a vacuum chamber in a fluorine gas mixture.

This is not a coating treatment but a chemical process, which roughens the substrate surface in the microscopic area, without changing the properties of the plastic part.

Fluorination is an irreversible activation of the surface, whose properties are stable over the long term.

Adhesion of paints

Only by activating a plastic surface by fluorination is good adhesion of paints possible.
