Kain Chemical: The role of wetting agents and wetting and dispersing agents in coatings

Wetting agents are surfactants, which are composed of hydrophilic and lipophilic groups. They can make solid materials more easily wetted by water. Wetting agents reduce the surface tension or interfacial tension of water so that water can spread on the surface of solid materials or penetrate into their surfaces, thereby moistening solid materials. When in…
