jr titanium white suppliers
R-906 rutile TiO2 has a high refractive index, which contributes to its superior whiteness and opacity. It also exhibits excellent lightfastness, ensuring that printed materials maintain their color and appearance over time. In addition, R-906 has a low oil absorption value, making it suitable for use in a wide range of printing ink systems.
In addition to pricing, businesses should also consider other factors when choosing a supplier, such as reliability, customer service, and delivery times. A supplier who is responsive to inquiries and can provide consistent quality products on time can make a big difference in the success of a business.
Transparent TiO2 is produced through a proprietary process that involves the controlled hydrolysis and oxidation of titanium tetrachloride. The resulting particles are micronized to achieve the desired particle size and distribution, which is critical for achieving optimal transparency and color performance.
This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists’ pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.
Scattering is strong when the difference in the refractive index of particle & matrix, Δn = np - nm, is big
The refractive index of binders used in coatings and inks is around 1.55. Titanium Dioxide is preferably used as a scattering source because the pigment does not absorb visible light and it has a high refractive index.
