Their liquid mixtures, usually containing water, alcohol and a surfactant, indicate a surface's energy by how they wet or disperse on it. Higher surface energy generally means better wettability and adhesion. The pens can check films, coatings, adhesives and plastic surfaces for printing, packaging, plastics, flexo, laboratory and quality-control work, including checks of corona or plasma treatment and production-line treatment.

They offer an alternative to applying liquid mixtures directly. Shelf life is six months; store them in a cool place.
