Overview
Rutile white pigment, primarily composed of titanium dioxide (TiO2), is a high-performance pigment renowned for its exceptional opacity and brightness. Derived from the rutile form of TiO2, it offers superior UV resistance and durability compared to anatase TiO2. This makes it a preferred choice for applications requiring long-term color stability and weather resistance. The pigment is available in both powder and slurry forms, with the slurry being easier to disperse in liquid formulations. Its versatility and performance characteristics have made it a staple in industries ranging from coatings and plastics to ceramics and cosmetics.
Physical and Chemical Properties
Rutile white pigment exhibits a high refractive index (~2.7), which contributes to its outstanding opacity and hiding power. Its chemical stability ensures resistance to acids, alkalis, and solvents, making it suitable for harsh environments. The pigment is thermally stable, with a melting point of approximately 1843°C, and remains inert under most conditions. Particle size distribution is a critical factor affecting its performance. Finer particles enhance brightness and gloss, while larger particles improve durability and scattering efficiency. The pigment's insolubility in water and most organic solvents further enhances its applicability in diverse formulations.
Main Applications
Rutile white pigment is extensively used in the coatings industry for architectural paints, automotive finishes, and industrial coatings. Its UV resistance and opacity make it ideal for outdoor applications. In plastics, it provides whiteness and opacity to products like PVC, polyolefins, and engineering resins. The ceramics industry utilizes the pigment for glazes and enamels, where high-temperature stability is essential. It is also a key ingredient in inks, paper coatings, and cosmetics, offering brightness and uniformity. Its non-toxic nature makes it suitable for food-contact materials and personal care products.
Safety and Storage
While rutile white pigment is generally considered safe, precautions should be taken to avoid inhalation of dust, which can cause respiratory irritation. Direct skin contact should be minimized, and protective equipment like gloves and masks should be used during handling. Storage conditions are critical to maintaining the pigment's quality. It should be kept in a cool, dry place, sealed in moisture-proof containers to prevent clumping or degradation. Bulk storage areas should be well-ventilated and free from contaminants to ensure product integrity.
B2B Procurement Guide
When procuring rutile white pigment, B2B buyers should prioritize purity, typically ranging from 90-99%, depending on the application. Particle size and distribution should align with the intended use, as these factors influence opacity, gloss, and dispersion characteristics. Suppliers often provide technical data sheets (TDS) and material safety data sheets (MSDS) for evaluation. Bulk purchases may offer cost advantages, but buyers should confirm storage and handling capabilities. Partnering with reputable suppliers ensures consistent quality and reliable supply chains.
