Surface Energy

Surface energy is a measure of the energy at a material's surface, influencing how it interacts with other substances, including liquids, powders, and gases. This property plays a crucial role in industries like pharmaceuticals, coatings, and adhesives, where adhesion, wetting, and cohesion are key to product performance and processing efficiency.

On this page, learn about the principles of surface energy, its measurement techniques, and its impact on industrial applications, from improving material adhesion to optimizing formulations.
