Effect of Polytetrafluoroethylene and Silicon oil on hydrophobicity of UV curable coatings

Hydrophobic coatings are essential in various industries for enhancing water repellency and contamination resistance for such applications like self-cleaning, corrosion resistance and anti-fogging. UV-curable coatings offer an efficient solution due to their rapid curing, low energy consumption, and minimal volatile organic compound (VOC) emissions. In this study, polytetrafluoroethylene (PTFE) powder and silicone oil were incorporated into a synthesized UV-curable epoxy acrylate resin to enhance surface hydrophobicity. Water contact angle (WCA) measurements were used to evaluate the effects of these additives. The results showed that adding ۱ wt.% PTFE increased the WCA to ۹۲°, while ۳ wt.% silicone oil improved it to ۱۰۰°. The optimized formulation, containing both ۱ wt.% PTFE and ۳ wt.% silicone oil, achieved the highest WCA of ۱۰۷°, demonstrating a synergistic enhancement in hydrophobicity. These findings suggest that modifying UV-curable coatings with PTFE and silicone oil is an effective strategy for improving surface properties in various applications.
