Characteristics
Silicon dioxide, also known as silica, is commonly used in the coating of matte paper to provide a smooth and matte finish.
It helps to improve the printability and ink absorption of the paper, resulting in sharper and more vibrant images. Silicon
dioxide also helps to enhance the durability and water resistance of the paper, making it suitable for a variety of printing
applications.
Silica Matting Agent is a type of chemical additive used in paper coating formulations to achieve a matte or satin finish on
the coated paper surface. It is composed of finely ground silica particles that are dispersed within the coating formulation.
When applied to the paper surface, silica matting agents help to reduce the gloss and reflectivity of the coating, resulting
in a duller appearance. This is desirable for certain applications where a matte finish is desired, such as in printing and
packaging materials, book covers, and specialty papers.
Silica matting agents work by scattering and diffusing light that falls on the coated surface, rather than reflecting it directly
back to the viewer. The size and shape of the silica particles can be adjusted to achieve different levels of matting effect,
ranging from a soft satin finish to a more pronounced matte appearance.
In addition to providing a matte finish, silica matting agents also offer other benefits in paper coating formulations. They can
improve the scratch resistance and durability of the coated surface, enhance ink receptivity and printability, and improve the
overall feel and touch of the paper.
Overall, silica matting agents are an important component in the formulation of paper coatings, allowing manufacturers to
achieve a wide range of desired surface finishes and properties in coated papers.
USING TIPS:
* Recommend dosage is 3%-8%. (Please adjust the dosage according to the actual product.)
* As different formulations and conditions, suggest the user to test and make sure the dosage before using.
