Coat Protection Film Paint Additive Silicon Dioxide Powder

What functions will silicon dioxide make in film paint?

Silica powder in paint protective films and paint additives is a functional filler commonly used in paint manufacturing. Here 

is a detailed explanation of their role and use in coatings:

Silica powder (SiO2)

1. Enhanced performance: Silica powder can significantly improve the hardness, wear resistance, chemical resistance and 

weather resistance of the coating. This is due to its high hardness and good chemical stability.

2. Improve leveling: Adding an appropriate amount of silica powder can improve the leveling of the paint and make the surface 

of the coating smoother.

3. Improve hiding power: The high refractive index of silica powder helps to improve the hiding power of paint and reduce 

the amount of paint, thereby reducing costs.

4. Anti-settling: In some coating systems, silica powder can be used as an anti-settling agent to prevent pigment particles 

from settling during storage.

5. Ultraviolet shielding: Silica powder has a good shielding effect on ultraviolet rays, which helps to improve the aging resistance 

of the coating.

Application in paint protective film

In paint protective films, the use of silica powder is particularly critical. Protective films usually need to have excellent physical and

mechanical properties and environmental resistance, and the addition of silica powder can significantly improve these properties

in particular:

- Enhance the wear resistance of the protective film: The high hardness of silica powder can effectively increase the wear resistance 

of the protective film and extend its service life.

- Improve scratch resistance: By improving the hardness and toughness of the film layer, silica powder can effectively reduce the

occurrence of scratches.

- Improved UV resistance: The UV shielding properties of silica powder help protect the substrate under the film from UV damage.

- Improve optical properties: By controlling the particle size and filling amount of silica powder, the transparency and gloss of the

protective film can be adjusted to meet the needs of different application scenarios.

In short, the application of silica powder in paint protective films and paint additives is mainly to optimize the overall performance 

of paint products by improving the physical and mechanical properties of materials, improving appearance effects, and enhancing 

anti-corrosion and anti-aging capabilities.
