Contact Angle of Powders Comparision of Methods

Contact Angle of Powders Comparision of Methods

The first step of dispersion and dissolution of a powder is wetting; therefore, understdanding the wettability behavior of powders is important in many applications such as inks, paints, food and pharmaceutical industry. The method to characterize powder wettability depends on the powder properties and application purposes. Sessile drop, Wilhelmy plate and liquid penetration (both column and thin film wicking) are common methods for determining the wettability of powders.

Solid Surface Free Energy

Solid Surface Free Energy

Solid surface free energy is one of the basic physical properties like density, melting point, refractive index, dielectric constant, modulus, etc. Measuring the solid surface free energy has applications in paints, coatings, and adhesives, semiconductors, printing, aerospace, mining, pharmaceutical and many more industries. To give an insight, high surface energy material is more reactive and stickier.
