Silica white powder is often used as a functional filler in water-based coatings. It is a type of amorphous silica that has a
high surface area and low oil absorption, making it ideal for improving the properties of coatings.
The addition of silica white powder to water-based coatings can provide several benefits, including:
1. Improved durability and scratch resistance: Silica acts as a reinforcing agent, enhancing the mechanical strength and
hardness of the coating. This can help protect the coated surface from scratches, abrasion, and wear.
2. Enhanced hiding power: Silica white powder has excellent hiding power, which means it can improve the opacity and
coverage of the coating. This is particularly important when coating surfaces with different colors or textures.
3. Increased surface smoothness: The fine particle size of silica white powder helps to fill in surface imperfections, resulting
in a smoother finish. This can improve the appearance and feel of the coated surface.
4. Anti-settling and anti-sagging properties: Silica white powder has a high thixotropic effect, which means it thickens the
coating when at rest but thins out when subjected to shear. This helps prevent settling of pigments and fillers during storage
and application, as well as reducing sagging on vertical surfaces.
5. Improved matting effect: Silica white powder can be used to create a matte or satin finish in water-based coatings. By
controlling the particle size and concentration of the silica, the gloss level of the coating can be adjusted to the desired level.
Overall, the addition of silica white powder to water-based coatings can enhance their performance and appearance, making
them more durable, smooth, and aesthetically pleasing.
USING TIPS:
* Recommend dosage is 3%-8%. (Please adjust the dosage according to the actual product.)
* As different formulations and conditions, suggest the user to test and make sure the dosage before using.
