Detailed Technical Parameters
High Purity:
The purity of JS-500 can reach 99%,it is quite high for precipitated silica.
BET Specific Surface Area:
The BET specific surface area of precipitated silica ranges is higher than 500 m²/g, indicating a large surface area that helps enhance interactions with other components, thereby improving the performance of the paint.
DBP Absorption Value:
The DBP absorption value ranges from 2.3 to 2.8 ml/g, reflecting the product's pore structure and adsorption capacity, which is crucial for the thickening and stability of coatings.
Soluble Salt (Na2SO4):
The soluble salt content is ≤0.5%, indicating high purity and reducing impurities that could affect the performance of the paint.
pH Value:
The pH value is controlled between 6.0 and 7.0, helping to maintain the stability of the paint system and avoid performance changes due to pH fluctuations.

Q&A :
What is the function of precipitated silica in coating and painting?
Firstly,as a thickening agent, precipitated silica can improve the viscosity of paints and coatings, enhancing their application and leveling properties.
Secondly,as a gloss enhancer, it can increase the glossiness of the coating, making the surface smoother and shinier.
