Feature
Silica dioxide, also known as silica or silicon dioxide, is a common Matting Agent used in water-based coatings. It is a
white, powdery substance that is derived from natural sources such as quartz or sand.
Matting agents are added to coatings to reduce gloss and create a matte or satin finish. They work by scattering and
diffusing light, which reduces the reflectivity of the coated surface. This can be desirable for aesthetic reasons or to improve
the hiding power of the coating.
Silica dioxide is particularly suitable for water-based coatings due to its compatibility with water-based systems. It can be easily
dispersed in water and incorporated into the coating formulation. It also has good stability and does not affect the performance
or properties of the coating.
In addition to its matting effect, silica dioxide also provides other benefits to water-based coatings. It can improve scratch
resistance, enhance surface hardness, and increase the durability of the coating. It also helps to prevent blocking, which is the
sticking together of coated surfaces when they come into contact.
Overall, silica dioxide is a versatile and effective matting agent for water-based coatings. It provides a matte or satin finish while
offering additional benefits to the coating's performance and durability.
