Precipitated Silica Used as a Matting Agent in Paints, Coatings, and Printing Inks
Product:Precipitated silica for painting and coating as matting agent
Introduction:
Function of SiO2 powder:
JS-280 acts as a matting agent by controlling the glossiness of paint and coatings. It is a precipitated silica that has a controlled layer thickness that optimizes light scattering. The layer thickness can be adjusted in such a way that it efficiently absorbs the light and decreases the reflectance value of the paint, resulting in a matte finish. Our product is an efficient substitute for wax and polymer-based matting agents, which often result in poor scratch resistance and worse dispersibility in coatings and inks.
Advantages of Using Precipitated Silica in Paints:
1. MATTE FINISH:it creates a matt appearance and finish, and is used as a substitute for conventional matting agents, which are known to cause problems like crawling, fish-eye, poor levelling and scratching due to its non-uniform behaviour, particularly in higher volumes.
2. GEL RING PREVENTION: it helps in preventing gel ring formation in high-solid coatings, which can cause a bad appearance.
3. PAINT FILM STRENGTH: it improves the paint film strength and gives it an efficient texture.
4. SAFETY AND HEALTH: it allows for safer handling of the paint since it is an amorphous silica which does not cause any harm or toxicity to the environment or humans.
