Wetting is the ability of a liquid to maintain and keep contact with a solid surface.<\/p>
Wetting deals with all the three phases of materials: gaseous, liquid and solid.<\/p>
The type and the different wettability value of a surface may result in a hydrophilic or hydrophobic surface. This value is usually measured by means of the \u201ccontact angles\u201d test.<\/p>
Super hydrophilic, which literally means \u201dstrong affinity for water\u201d, gives maximum wetness to the surface.<\/p>
On the other side, wetness is lacking in case of a super hydrophobic surface, thus promoting single and isolated drops formation.<\/p>
All wetting agents create the proper condition to adequately wet a surface. They are usually made of organic molecules that act both in the interphase between the ceramic support and glaze and in the interphase between the glaze and the air: the leveling action they promote is, for example, specifically produced by decreasing the surface tension of water in the glaze\/air inter-phase.<\/p>","protected":false},"excerpt":{"rendered":"
