Product Description
High grade silica dioxide is often used in paper spray coating applications due to its unique properties and benefits. Silica
dioxide, also known as silica or silicon dioxide, is a naturally occurring mineral that is commonly found in sand, quartz, and
many other minerals.
When used in paper spray coating, high grade silica dioxide offers several advantages:
1. Improved Coating Uniformity: Silica dioxide particles have a small particle size and high surface area, which allows for
better dispersion and coating uniformity on the paper surface. This results in a more even and consistent coating, leading to
improved print quality and ink adhesion.
2. Enhanced Ink Absorption: Silica dioxide has a porous structure that can absorb ink pigments, binders, and other additives
present in the coating formulation. This helps to reduce ink bleed, improve color vibrancy, and enhance the overall print quality.
3. Increased Coating Strength: Silica dioxide particles can strengthen the paper coating by acting as a filler material. They
improve the mechanical properties of the coating, such as its tensile strength and tear resistance, making the paper more
durable and resistant to handling and transportation.
4. Improved Printability: The presence of silica dioxide in the coating formulation can improve the surface smoothness of the
paper, reducing the roughness and unevenness that can negatively affect printability. This results in sharper and more detailed
prints, with better ink transfer and reduced dot gain.
5. Environmental Benefits: Silica dioxide is a naturally occurring mineral and is considered safe for use in paper coatings. It is
non-toxic, non-flammable, and does not release harmful emissions during the coating process. Additionally, silica dioxide is
biodegradable and does not contribute to environmental pollution.
Overall, high grade silica dioxide is a valuable additive in paper spray coating applications, providing improved coating uniformity, enhanced ink absorption, increased coating strength, improved printability, and environmental benefits. Its unique properties make
it an ideal choice for achieving high-quality paper coatings in various printing and packaging applications.
