WebDec 23, 2024 · This means that the glass surface will look a little like water, i.e, the effective cohesive energy of the surface will be a little less like pure glass and slightly more like water. In the battle for water, the drop will still win but the hydrated glass gets in a few licks. The glass likes glass a lot and is not itself dissolved by the water. WebWater does not wet waxed surfaces because the cohesive forces within the drops are stronger than the adhesive forces between the drops and the wax. Water wets glass and spreads out on it because the adhesive forces between the liquid and the glass are stronger than the cohesive forces within the water. Formation of a Meniscus
WebGood wettability of glass is undesirable in many applications, for example for car windshields or spectacle lenses. In such cases, glass is often given a hydrophobic coating. Our measuring technology is used in the development and testing of non-stick coatings. Applications of surface analyses for glass.
