Feature
High purity silica dioxide is the main material of matte coating. It is made up to silicon atom and oxygen atom which
appearance is white color powder. Silica dioxide is famous for its high reflection. With this ability, it can create an excellent
light disperation. And it is very suitable to create matte coating in the colorful coatings.
In matte coatings, using silica dioxide can reduce the glossiness of the coating which can create a matte appearance.
High purity silica dioxide is the first choice of matte coatings cause it has the stable performances.
The silica dioxide with inrelated elements will effect the apperance and the ability of the coatings. Silica dioxide is added into
the coating by specific ratio to achieve the desired level of matte effect.
In addition to use silica dioxide into the matte coatings, high purity silica dioxide is also wide using in other applications like
paintings, ink, adhesive and plastics. Its versatility and excellent light scattering properties make it a valuable
ingredient in many industries.
