Precipitated silica has shown significant stabilizing and thickening effects in the coating industry, mainly due to its unique physical and chemical properties. The following is a detailed analysis of these two effects:

1. Stabilizing effect
Anti-sedimentation:
Precipitated silica has a high specific surface area and small particle size, which enables it to be effectively dispersed in the coating system to prevent the sedimentation of pigments and fillers. Its good dispersion uniformity helps maintain the stability of the coating and prevents stratification or precipitation during use.

Thixotropy:
Thixotropy is a property of the coating that changes in viscosity when subjected to shear force. Precipitated silica can give the coating stable thixotropy, that is, it maintains a high viscosity when stationary to prevent sagging, and reduces the viscosity when stirred or brushed for easy construction. This property is of great significance to improving the construction performance of the coating and the quality of the final coating.
Anti-sagging:
During the coating construction process, sagging is a common problem that will cause uneven coating and affect the appearance. Precipitated silica can effectively prevent the sagging of the paint through its thickening and thixotropic effects, ensuring the flatness and beauty of the coating.

2. Thickening effect
Thickening effect:
As a highly efficient thickener, precipitated silica can increase the viscosity of the paint without increasing the amount of solvent. Its thickening effect mainly comes from the interaction between its particles and the interaction between the particles and other components in the paint. These effects together form a stable network structure, thereby increasing the overall viscosity of the paint.
Improving fluidity:
Although precipitated silica has a thickening effect, it does not significantly affect the fluidity of the paint. On the contrary, due to its good dispersibility and thixotropy, it can maintain good fluidity of the paint while ensuring the viscosity of the paint, making the construction smoother.
Improving film performance:
The thickening effect of precipitated silica also helps to improve the performance of the film. On the one hand, the thickened paint can better fill the tiny defects on the surface of the substrate during the film formation process, improving the flatness and smoothness of the film; on the other hand, the thickened paint can better form a continuous film layer during the drying process, improving the hardness and wear resistance of the film.

In summary, precipitated silica has shown excellent stabilization and thickening effects in the coatings industry. These effects not only improve the coating's construction performance and the quality of the final coating, but also reduce production costs and environmental pollution risks. Therefore, precipitated silica has broad application prospects and market demand in the coatings industry.
