Improving Hydrophilicity of Glass Using Plasma
Plasma treatment glass surfaces effectively improves glass hydrophilic properties by increasing surface energy and creating polar functional groups that attract water. This process reduces contact angle of water on glass from over 90° to under 30°, converting hydrophobic glass into hydrophilic surfaces for improved printing, coating, and bonding applications. Plasma treating offers a clean, environmentally […]
Understanding Contact Angle: A Key to Evaluate Surface Wetting
Contact angle measures how well liquids spread on surfaces. When you place a water droplet on a surface, the angle it forms tells you about surface properties. Low contact angles (under 90°) mean good wettability because liquids spread easily. High contact angles (over 90°) mean poor wettability because liquids bead up. For manufacturers using surface […]
