Product introduction:
Silicon dioxide, also known as silica, has several uses in matte paper coating. Some of these uses include:
1. Coating Agent: Silicon dioxide is commonly used as a coating agent in matte paper production. It provides a smooth
and even surface to the paper, enhancing its printability and improving the overall appearance of the finished product.
2. Opacity Enhancer: Silicon dioxide can also be used as an opacity enhancer in matte paper coating. By adding silica to the
coating formulation, the paper becomes less transparent, reducing the show-through of text or images from the other side of
the paper.
3. Ink Absorption: Silicon dioxide has a high ink absorption capacity, making it an ideal additive for matte paper coating. It
helps to prevent ink from spreading or bleeding on the paper surface, resulting in sharper and more defined print quality.
4. Surface Roughness Modifier: Silicon dioxide can be used to modify the surface roughness of matte paper. By controlling
the particle size and distribution of silica, the coating can be adjusted to achieve the desired level of surface smoothness or
texture.
5. Anti-blocking Agent: Silicon dioxide is often used as an anti-blocking agent in matte paper coating. It helps to prevent the
sticking or blocking of sheets of paper when stacked together, improving the handling and usability of the finished product.
Overall, silicon dioxide plays a crucial role in matte paper coating by improving printability, opacity, ink absorption, surface
roughness, and anti-blocking properties.
