Silica white powder is a commonly used additive in water-based coatings. It is primarily used to improve the flow and leveling
properties of the coating, as well as to enhance its durability and resistance to abrasion.
The silica white powder used in water-based coatings is typically made up of 99% pure silica, which is a naturally occurring mineral
found in various forms, such as quartz and sand. Silica has excellent properties that make it suitable for use in coatings, including
its high hardness, chemical inertness, and low oil absorption.
When added to water-based coatings, the silica white powder acts as a Matting Agent, helping to reduce the glossiness of the
coating and create a more matte or satin finish. It also helps to improve the viscosity and rheology of the coating, ensuring that it
spreads evenly and smoothly over the surface being coated.
In addition to its matting and leveling properties, silica white powder also enhances the durability and abrasion resistance of
water-based coatings. It forms a strong and hard film when the coating dries, which helps to protect the underlying surface from
damage caused by wear and tear.
Overall, the use of 99% content silica white powder in water-based coatings offers several benefits, including improved flow and
leveling, enhanced durability, and a more matte or satin finish. It is a versatile additive that is commonly used in various applications,
such as architectural coatings, automotive coatings, and industrial coatings.
