Contact angle

Wettability is the degree to which a liquid maintains contact with a solid surface. It is crucial for coatings and adhesives, since it directly impacts adhesion and bonding. Better bonding enables stronger and more consistent applications. The wettability of a surface is quantified by the contact angle between drop and surface. It ranges from hydrophobic (high angle) to hydrophilic (low angle).
