In February 2026, relevant research deeply analyzed the mechanism of polymeric wetting and dispersing agents in pigment stabilization. As a kind of interfacial active agent with dual functions of wetting and dispersing, it has become a core additive in coatings, inks, plastics and other fields, effectively solving the industry pain points of uneven pigment dispersion and easy agglomeration. Relying on its amphiphilic structure of hydrophilic and lipophilic groups, it plays a key role in the three stages of wetting, dispersion and stabilization. It can reduce the surface tension of aqueous solution to below 40mN/m in room temperature aqueous system, greatly improving the wettability of pigments. In the stabilization stage, it relies on the synergistic effect of three mechanisms: electrostatic repulsion, steric hindrance and electrosteric hindrance, which prevent pigment agglomeration through charge repulsion, physical barrier and composite effect respectively, adapting to different dispersion systems. At present, high molecular weight products with molecular weight of 5000-30000g/mol have become the research focus. Their anchoring groups and polymer chains can be precisely regulated, showing outstanding performance in high-end scenarios such as automotive coatings. With the development of materials science, the additive will continue to be optimized and upgraded, with an increasingly broad application prospect.
