Brief performance introduction and classification of wetting agent

A substance added to a liquid to reduce its surface tension. Surfactants that can wet liquids or accelerate the wetting of solid surfaces are called wetting agents. The HLB value is around 10.

wetting agent

The performance that wetting agent should have

A substance that makes solid materials more wettable by water. By reducing its surface tension or interfacial tension, water can be spread on the surface of the solid material or poured into its surface to wet the solid material.

Wetting principle Wetting agents are composed of hydrophilic groups and lipophilic groups. The base extends outward into the liquid, so that the liquid forms a continuous phase on the solid surface, which is the basic principle of wetting.

Wetting agents are divided into two categories according to their properties

Wetting agents include anionic and nonionic surfactants.

Anionic surfactants include alkyl sulfates, sulfonates, fatty acid or fatty acid ester sulfates, carboxylic acid soaps, phosphate esters, etc.

Nonionic surfactants include polyoxyethylene alkylphenol ether, polyoxyethylene fatty alcohol ether, polyoxyethylene polyoxypropylene block copolymer, etc.
