Properties of Teflon: Non-Wetting

DuPont Teflon® industrial coatings are highly durable and long lasting performance coatings that have a distinct application process and qualities that offer solutions in a variety of industrial markets.   This series of blogs will highlight one of these inherent properties of Teflon®  coatings and how these properties can solve a variety of problems. 

Non-Wetting: Teflon® coatings are both hydrophobic and oleophobic, making cleanup easier and more thorough. Hydrophobic substances repel the polar ions in water and resist wetting. The low surface energy of the coatings means that the cohesive forces in the water are strong enough to make the water bead up and not spread across the surface of the coating. This property of Teflon® coatings is especially important for coating laboratory glassware, such as beakers and test tubes, in order to minimize cross-contamination. PTFE shows the best non-wetting characteristics.
