WETTING

(1) The power of a vehicle to spread uniformly and rapidly over the surface of pigment particles. A vehicle with good wetting properties assists in the grinding or dispersion of pigments and the ability to wet the surface to which the coating is applied ; (2) The ability of the coating being applied to come into physical contact with the existing coating or oxide layer. Good wetting depends on the relative surface tensions of the two surfaces.
