High grade silica dioxide is commonly used as a filler or reinforcing agent in various products, including coatings, adhesives,
plastics, and rubber. It is also used as a thickening agent in some formulations.
In the case of matt hardeners, high grade silica dioxide can be added to the formulation to help improve the hardness and
durability of the final product. It can also enhance the matte finish of the coating or adhesive, giving it a more desirable
appearance.
Silica dioxide has excellent mechanical properties, such as high tensile strength and abrasion resistance, which make it ideal
for use in hardeners. It can also improve the adhesion of the coating or adhesive to the substrate, resulting in a stronger and
more durable bond.
Furthermore, high grade silica dioxide has a low refractive index, which means that it does not reflect light as much as other
materials. This property helps to reduce the glossiness of the coating or adhesive, giving it a matte or satin finish.
Overall, high grade silica dioxide is a versatile and effective additive for matt hardeners, providing improved hardness, durability,
adhesion, and matte appearance to the final product.
