<p>The seal (1) has a sealing lip (2) partially provided with a coating (3) to control wettability of the seal with respect to polar and/or non-polar media, where the coating is formed in a functional region (4) or at a free end of the sealing lip. The sealing lip is produced from polytetrafluoroethylene compound or glass fibers. The coating is formed from a perforated surfactant particles, fluorine polymer or alkoxysilane using a plasma treatment, where the contact angle of the polar and/or non-polar media in the region of the coating is greater than 90 degrees.</p> |
