TITANIUM DIOXIDE
TITANIUM DIOXIDE
Chemical Formula: TiO?
Molecular Weight: 79.87 g/mol
Description:
Titanium Dioxide is a white, odorless, inorganic compound with high brightness and excellent opacity. It exists mainly in two crystalline forms — Rutile and Anatase. Known for its superior covering power, UV resistance, and chemical stability, it is widely used as a white pigment and opacifier in paints, coatings, plastics, papers, inks, and cosmetics.
Applications:
-
Paints & Coatings: Primary white pigment providing high opacity, brightness, and weather resistance.
-
Plastics & Rubber: Used as a whitener and UV stabilizer in plastic formulations.
-
Paper Industry: Enhances whiteness and opacity in coated and specialty papers.
-
Printing Inks: Improves color strength and brightness.
-
Cosmetics & Personal Care: Used in sunscreens, creams, and powders for UV protection.
-
Ceramics & Textiles: Provides whiteness and improves surface finish.
