Silicon Dioxide Powder Used In Water Based Primer

Feature

Silicon dioxide powder, also known as Silica Powder, is commonly used in water-based primers for several reasons:

1. Filler: Silicon dioxide powder acts as a filler in water-based primers, helping to improve the coverage and hiding power 

of the primer. It fills in small imperfections on the surface, creating a smooth and even base for the topcoat.

2. Adhesion: Silicon dioxide powder enhances the adhesion of the primer to the substrate. It forms a strong bond between 

the primer and the surface, ensuring better paint adhesion and durability.

3. Thixotropic agent: Silicon dioxide powder can also act as a thixotropic agent, which means it helps to control the viscosity 

of the primer. It prevents the primer from dripping or running during application, allowing for better control and easier 

application.

4. Anti-settling agent: Silicon dioxide powder helps to prevent settling of pigments and other solid particles in water-based 

primers. It keeps the particles suspended evenly throughout the primer, ensuring consistent color and performance.

5. Abrasion resistance: Silicon dioxide powder enhances the abrasion resistance of water-based primers. It forms a hard and 

durable film that can withstand wear and tear, making the primer more long-lasting and resistant to damage.

Overall, silicon dioxide powder plays a crucial role in improving the performance, appearance, and durability of water-based 

primers.
