Titanium Dioxide Kronos

Product Description

Specification

Titanium Dioxide, commonly known as titanium white, is a white, non-toxic, and chemically stable inorganic pigment. It is recognized as the world's premier white pigment due to its exceptional whiteness, brightness, covering power (opacity), and strong resistance to chalking. It is widely used in numerous industries such as coatings, plastics, paper, inks, synthetic fibers, rubber, ceramics, and cosmetics.

PH	6.5-8.5

Titanium Dioxide is primarily classified into two types based on its crystal structure and production process:

· Rutile
  · Characteristics: Features a denser crystal structure and a higher refractive index (approx. 2.76), resulting in superior hiding power, weather resistance, and anti-chalking properties.
  · Applications: Primarily used in exterior applications requiring high durability and opacity, such as architectural exterior coatings, automotive paints, industrial coatings, and plastic window profiles/rigid PVC.
· Anatase
  · Characteristics: Has a less compact crystal structure and a lower refractive index (approx. 2.55). It offers a slightly higher base whiteness but poorer lightfastness and weatherability. Prolonged UV exposure can cause chalking and yellowing.
  · Applications: Mainly used for indoor products with low weather resistance requirements, such as interior paints, paper filling and coating, rubber, synthetic fibers, and cosmetics.

3. Key Properties & Advantages

1. Exceptional Whiteness & Brightness: Provides a pure, bright white base and enhances the vividness of other colors.
2. High Hiding Power (Opacity): Its high refractive index allows it to efficiently scatter and reflect light, enabling complete coverage of underlying surfaces with minimal product usage, saving material costs.
3. Excellent Weatherability: Especially Rutile grades, which resist degradation from UV radiation, rain, chemicals, and temperature variations, protecting the substrate and extending product life.
4. Chemical Stability: Insoluble in weak acids, weak bases, and organic solvents. It does not react harmfully with binders or other formulation components.
5. Strong Tinting Strength: Provides powerful coloring effects while maintaining color purity.
6. Good Dispersibility: Surface-treated for easy and uniform dispersion in various media, forming stable and smooth systems.

4. Primary Applications

Industry Primary Function & Benefit
Coatings Industry Provides opacity, whiteness, durability, and gloss for architectural paints (interior & exterior), industrial coatings, automotive finishes, marine paints, and coil coatings.
Plastics Industry Imparts opacity, whiteness, and heat stability for PVC profiles, windows, home appliances, toys, packaging films, and masterbatches.
Paper Industry Used as a filler and coating pigment to improve paper whiteness, opacity, smoothness, and gloss for high-grade printing paper, art paper, etc.
Inks Industry Used in white inks and for tinting various colored inks, providing excellent hiding power and rheology.
Synthetic Fibers Acts as a delustering agent added to synthetic fibers (e.g., polyester) to eliminate harsh gloss and give a natural matte appearance.
Cosmetics & Personal Care Valued for being non-toxic, highly white, and opaque, it is widely used in foundations, sunscreens, face powders, and toothpaste.
Rubber Industry Serves as a white pigment and reinforcing filler, also providing anti-aging properties.
Food & Pharmaceuticals High-purity grades are used as a white colorant in pharmaceutical tablet coatings and food products (e.g., chewing gum, candy coatings), subject to regulatory compliance (e.g., FDA).

6. Packaging & Storage

· Packaging: Standard packaging is 25 kg multi-layer paper bags with an inner plastic liner. Other options include 500 kg or 1-ton jumbo bags and bulk tanker trucks, subject to customer requirements.
· Storage: Store in a cool, dry, and well-ventilated warehouse. Protect from moisture and rain. Avoid storage with acids, alkalis, or other chemicals.

7. Health & Safety Information

· Safety: Titanium Dioxide is non-toxic, odorless, and generally considered a safe material. Approved grades are used in food and cosmetics (e.g., E171).
· Dust Control: However, dust may be generated during handling. Inhalation of high concentrations of dust over prolonged periods may cause mechanical irritation to the respiratory system.
· Handling Precautions: Operate in a well-ventilated area. Use appropriate personal protective equipment (PPE), such as a dust mask and safety glasses, to prevent inhalation and eye contact.
