“The World’s First Evaluation of the Sliding Motion of Water Droplets on Hydrophobic Surface”: Here is notable new Dynamic Sliding Angle Method release. Kyowa serve you not only currently used Sliding Angle Method but also integrated evaluation of dynamic hydrophobicity of solid surface by monitoring the sliding behavior of droplet taking into the consideration of time parameter.
“Wettability and repellency are research subjects at the border between physics and chemistry, and are important properties of solid surfaces from both fundamental and practical aspects. While the contact angle of water has been commonly used as a criterion for evaluating the static hydrophobicity of the surface, this alone is inadequate for evaluating the dynamic hydrophobicity, which is the sliding behavior of water droplets. Recently, recognition of the importance of dynamic hydrophobicity is growing in various industries such as the glass, automobile, and electronics industries. So far, the sliding angle (the angle when a droplet of water of a certain weight begins to slide down an inclined plate) is commonly employed as a criterion for assessing the dynamic hydrophobicity of a solid surface.”（ Dr. A.
