SiO2, also known as silicon dioxide or silica, can be used as a Matting Agent in water-based coatings. Matting agents are
used to reduce the gloss or shine of a coating and create a matte or satin finish.
SiO2 particles can be incorporated into water-based coatings to create a rough or textured surface, which scatters light and
reduces the glossiness of the coating. This can be achieved by either using nano-sized SiO2 particles or by modifying the
surface properties of larger SiO2 particles.
The addition of SiO2 as a matting agent in water-based coatings offers several advantages. Firstly, SiO2 is an abundant and
cost-effective material. It is also chemically inert and has good thermal stability, making it suitable for various coating applications.
Additionally, SiO2 particles can be easily dispersed in water-based systems, ensuring uniform distribution throughout the coating.
Furthermore, SiO2 matting agents can provide enhanced scratch resistance and improved durability to the coating. The rough
surface created by SiO2 particles can also help to reduce the visibility of surface imperfections and provide a more aesthetically
pleasing finish.
However, it is important to note that the effectiveness of SiO2 as a matting agent may vary depending on factors such as particle
size, concentration, and coating formulation. Therefore, it is recommended to conduct thorough testing and optimization to achieve
the desired level of matting effect in water-based coatings.
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.
