What is the specific amount of precipitated silica added to paint?

The recommended addition amount of precipitated silica in paint is usually 1.5% to 7.0% of the total formula.

The amount of silica added by precipitation method varies in different types of paints. For example, in unsaturated polyester coatings, adding 0.5% to 2.0% precipitation method silica can achieve the desired effect; Adding 0.5% precipitated silica to printing ink can significantly improve the printing effect. In addition, the amount of precipitated silica used as a matting agent in the lacquer system needs to be adjusted according to specific physical and chemical parameters. Overall, the amount of precipitated silica added varies depending on the type of coating and performance requirements.
