TITANIUM DIOXIDE FOR PAINT

Key functions of TiO2cap T i cap O sub 2???2 in paint 

• Opacity (Hiding power): TiO2cap T i cap O sub 2???2 is highly effective at scattering light, which provides the paint with its hiding power. This allows for fewer coats to achieve full, even coverage.
• Whiteness and brightness: It acts as the primary white pigment, creating a vivid white color base that can be tinted to produce clean and bright hues.
• Durability and weather resistance: In exterior paints, TiO2cap T i cap O sub 2???2 protects the paint film by absorbing and scattering harmful ultraviolet (UV) radiation. This prevents the binder from degrading, which in turn resists cracking, fading, and chalking.
• Chemical stability: TiO2cap T i cap O sub 2???2 is chemically inert and highly stable, ensuring the paint maintains its color and finish over time without yellowing.
• Corrosion resistance: For industrial and marine coatings, TiO2cap T i cap O sub 2???2 improves the paint's ability to act as a barrier against corrosive elements, extending the life of the painted surface.
• Gloss: The smooth, fine particles contribute to the overall smoothness and gloss of the final paint finish. 

Grades of TiO2cap T i cap O sub 2???2 for paint TiO2cap T i cap O sub 2???2 is available in two main crystal forms, rutile and anatase, with rutile being the most common for high-performance paints. Specific grades are engineered for different applications through particle-size control and surface treatments with materials like alumina and silica. 

Grade Type	Characteristics	Typical Applications
Rutile	Offers superior light scattering, UV protection, and durability due to its higher refractive index.	Most high-performance paints, especially exterior architectural, industrial, and automotive coatings.
Anatase	Provides excellent brightness at a lower cost than rutile but offers less durability and UV resistance, making it more photoactive.	Inexpensive interior paints or primers where weather resistance is not a concern.

Alternatives to TiO2cap T i cap O sub 2???2 While no single pigment can fully replace TiO2cap T i cap O sub 2???2 due to its unique combination of properties, partial substitutes are used to reduce costs, particularly in low-end and high-PVC (Pigment Volume Concentration) paints. 

Alternative	Pros	Cons
Barium sulfate	Acts as an effective spacer for TiO2cap T i cap O sub 2???2 particles, improving scattering efficiency and allowing for lower TiO2cap T i cap O sub 2???2 content. Used in a super-white paint developed for passive cooling.	Lower refractive index and significantly less opacity and b
