Description

Rutile CAS NO 1317-80-2 is the naturally occurring and most thermodynamically stable crystalline form of titanium dioxide (TiO₂). This high-performance pigment and functional material is valued for its exceptional durability, high refractive index, and superior UV light absorption properties. It is a critical raw material for industries requiring long-lasting whiteness, opacity, and photocatalytic activity, including paints and coatings, plastics, cosmetics, and advanced ceramics.

Application

• Paints, Coatings, and Inks: Primary white pigment providing excellent opacity, brightness, and weather resistance for architectural, industrial, and automotive applications.
• Plastics and Masterbatches: Used as a whitening and UV-blocking agent to enhance the durability and color stability of polymers, films, and fibers.
• Cosmetics and Personal Care: Key ingredient in sunscreens and makeup for its effective broad-spectrum UV protection and skin feel.
• Ceramics and Enamels: Imparts whiteness, opacity, and acid resistance to glazes, sanitaryware, and technical ceramics.
• Paper Manufacturing: Acts as a high-quality coating and filler to improve printability, brightness, and opacity of premium paper grades.
• Photocatalysts and Environmental Purification: Utilized in air and water purification systems due to its photocatalytic properties under UV light.
• Welding Electrode Coatings: A crucial component in flux coatings for arc welding electrodes to stabilize the arc and improve weld quality.
• Rubber and Elastomers: Functions as a reinforcing filler and whitening agent in various rubber products.
