Feature
Silica matting agents are fine particles of silica that are used to reduce the gloss or shine of a coating or paint. They are
commonly used in various industries, including paints, coatings, inks, and plastics.
The main purpose of silica matting agents is to create a matte or satin finish on the surface of a coating or paint. They work
by scattering and diffusing light, which reduces the reflection and glossiness of the surface.
Silica matting agents are typically added to coatings or paints in small amounts, usually ranging from 1% to 10% by weight.
The exact amount depends on the desired level of matting effect.
There are different types of silica matting agents available, including precipitated silica, Fumed Silica, and silica gel. Each
type has its own characteristics and advantages, such as particle size, porosity, and surface treatment, which can influence
the matting effect and other properties of the coating or paint.
In addition to reducing gloss, silica matting agents can also provide other benefits, such as improving scratch resistance,
enhancing adhesion, and increasing hardness. They can also be used to control the flow and leveling of a coating or paint.
Overall, silica matting agents are an important additive in the coatings and paints industry, as they allow manufacturers to
achieve a wide range of desired finishes and properties in their products.
In economical site, silica dioxide is popular for its low cost and various choices.Silica dioxide can be got in sand which is
one of the most abundant minerals on Earth.
Comparing with other coating additives, choosing silica dioxide as additive is an ideal choice.Adding silica dioxide into the
coating can reduce the gloss and create a matte or satin finish.
