Product Introduction
High grade silicon dioxide is commonly used as a coating material for cast coated paper. Cast coated paper is a type
of paper that has a highly glossy and reflective surface, similar to the appearance of a mirror. This is achieved by applying
a layer of high grade silicon dioxide onto the surface of the paper.
Silicon dioxide, also known as silica, is a compound made up of silicon and oxygen atoms. It is a naturally occurring mineral
and is commonly found in the form of quartz. High grade silicon dioxide is usually obtained through a refining process to
ensure its purity and quality.
When applied to cast coated paper, the silicon dioxide coating enhances the paper's smoothness, glossiness, and whiteness.
It also improves the paper's printability and ink adhesion, making it suitable for high-quality printing applications such as
magazines, brochures, and packaging materials.
The high grade silicon dioxide coating on cast coated paper provides several benefits, including:
1. Enhanced gloss and reflectivity: The silicon dioxide coating creates a highly glossy and reflective surface, giving the paper
a premium appearance.
2. Improved print quality: The smoothness and ink receptivity of the silicon dioxide coating allow for sharp and vibrant printing
results.
3. Increased durability: The silicon dioxide coating adds a protective layer to the paper, making it more resistant to scratches,
smudges, and moisture.
4. Enhanced ink adhesion: The silicon dioxide coating helps the ink adhere better to the paper, resulting in sharper images and
text.
5. Improved resistance to aging and yellowing: The silicon dioxide coating helps to prevent the paper from yellowing or
deteriorating over time, ensuring its longevity.
In conclusion, high grade silicon dioxide is a crucial component in the production of cast coated paper. Its use as a coating
material enhances the paper's appearance, printability, and durability, making it a preferred choice for various high-quality
printing applications.
