Contact angle hkust
WebA contact angle gives us an indication of how well (or how poorly) a liquid will spread over a surface. While formulating an ink, contact angles provide a useful indicator of how a modification to the ink will affect its spreading. A contact angle can be large or small, depending on the physical properties of the materials being investigated. WebFor enquiry about nano-measurement, please contact Mr. Leo LEE (2358 8665).
