WebApr 28, 2024 · Ethanol, ionic liquids, dyes, protein, reduce surface tension of water, however these chemicals increase viscosity so it is better to deal with friccohesity. The surface tension and viscosity determinations need density data measurements but friccohesity does not. The deepest mechanistic changes are accurately resolved by friccohesity. WebSurface tension is the key parameter which determines good leveling and wetting of a coating. Surface tension is involved in almost every way in coatings technology i.e., dispersing, wetting, leveling, adhesion, etc. Infact, the appearance of surface defects on the coated surface is also governed by the surface tension of the materials (coating ...
