Properties of products
Hiding power: The most prominent thing about titanium dioxide is that it has a strong hiding power.
Tinting strength and Reducing power (Whiteing power, Achromatic) : Coloring power refers to its ability to change the color of a paint and present its own color after it is added to the paint.
Whiteness: Whiteness is the ratio between the absorption and reflection of visible light.
Oil absorption: Oil absorption is an important pigment property of titanium dioxide.
Dispersion: Dispersion is also known as grinding dispersion or grinding wetness.
Application area
TiO2 is a white pigment with the best performance, and its main application areas are coating, plastic and paper, ceramics, glass, alloy, welding electrode, rubber, fiber, oil Zhao, cosmetics and other industries.
