Anti-settling Agent

Anti-settling agents are primarily used to prevent the settling of solid particles such as pigments and fillers during storage, transportation, or use, ensuring the stability and uniformity of coatings. Since pigments and fillers typically have a higher density than the coating system, these particles easily settle within the coating, leading to uneven distribution and affecting the coating's quality and performance. Anti-settling agents work by adjusting the rheological properties of the coating or stabilizing the particle dispersion system, slowing down or preventing particle settling, thus effectively ensuring the coating remains stable during storage and use.

The working principle of anti-settling agents is mainly achieved through two methods to achieve stable particle dispersion: first, by increasing the viscosity of the coating, slowing its flow and making it less prone to particle settling; second, by enhancing the spatial repulsion or surface adsorption between particles, reducing the mutual attraction between particles, ensuring that the particles remain uniformly suspended. These mechanisms help prevent settling and stratification, ensuring that the coating maintains good performance and uniformity before production, storage, and use, thereby improving the application effect and product quality of the coating.

Anti-settling agents are widely used in high-pigment-content coating systems, such as architectural coatings and industrial coatings. They can significantly improve the storage stability of coatings, extend their shelf life, and prevent uneven coating due to sedimentation or stratification, which can affect application results and film quality. For coatings requiring long-term storage, the use of anti-settling agents is particularly important, ensuring that the coating maintains a stable dispersion during storage and transportation, preventing particle sedimentation from affecting the final coating effect.
