Excellent Cast Coated Paper Coatings Material Silica Powder

Feature 

Silica Powder is an excellent material for cast coated paper coatings due to its unique properties. Here are some reasons 

why silica powder is a preferred choice for this application:

1. High opacity: Silica powder has a high refractive index, which helps in achieving excellent opacity in the coated paper. 

This property is essential for producing vibrant and sharp prints.

2. Smooth surface: Silica powder has a fine particle size distribution, resulting in a smooth and glossy surface when applied 

as a coating. This smoothness enhances the print quality and provides a luxurious feel to the paper.

3. Improved ink holdout: Silica powder has a high porosity, allowing it to absorb and hold ink effectively. This feature prevents 

ink from spreading or bleeding on the paper, resulting in crisp and well-defined prints.

4. Enhanced print gloss: Silica powder can significantly improve the glossiness of the coated paper. It acts as a light diffuser, 

scattering light uniformly across the surface, which enhances the overall visual appeal of the prints.

5. Improved print durability: Silica powder provides excellent abrasion resistance, preventing the prints from smudging or 

rubbing off easily. This durability ensures that the prints maintain their quality even after handling or transportation.

6. Environmental friendliness: Silica powder is a naturally occurring mineral and is considered environmentally friendly. It is 

non-toxic, non-hazardous, and does not release any harmful substances during the paper production process.

Overall, the use of silica powder as a coating material for cast coated paper offers numerous benefits, including high opacity,

smooth surface, improved ink holdout, enhanced print gloss, improved print durability, and environmental friendliness.
