Product Description
Silica dioxide, also known as silicon dioxide or silica, is commonly used as a coating agent for paper. It is a white, powdery
substance that is derived from natural sources such as quartz or sand.
When used as a coating agent, silica dioxide helps improve the paper's smoothness, brightness, and printability. It forms a
thin layer on the paper surface, filling in any unevenness or pores, resulting in a smoother and more uniform surface. This
enhances the paper's ability to hold ink and improves the print quality.
Additionally, silica dioxide can increase the opacity of paper, reducing the show-through of text or images from the other side
of the page. This is particularly important for double-sided printing or when using thin paper.
Silica dioxide also provides some level of water resistance to the paper, making it more resistant to smudging or smearing when
exposed to moisture. This can be beneficial for applications such as packaging or labels.
Furthermore, silica dioxide can enhance the paper's durability and strength, making it less prone to tearing or wrinkling. This can
be particularly useful for high-quality papers or those intended for heavy use.
Overall, the use of silica dioxide as a coating agent for paper provides several benefits, including improved smoothness, printability,
opacity, water resistance, and durability. It is a widely used and effective additive in the paper industry.
