Titanium dioxide R-706
Product Description
Titanium dioxide R-706 is a universal rutile titanium dioxide pigment, manufactured by the chloride process, that is designed to deliver both high gloss and excellent durability in coatings. This outstanding combination of end-use performance properties makes it a versatile pigment in solvent and waterborne systems for architectural, industrial, and automotive applications. Titanium dioxide R-706 has the following general properties.

• Easy wet-in
• Super durability
• Good hiding
• Excellent dispersibility
• Blue undertone
High Gloss
Careful control of the Titanium dioxide R-706 particle size during manufacture of R-706 results in exceptional gloss performance. Titanium dioxide R-706 has a tight particle size distribution, resulting in less oversized particles that detract from gloss.
Super Durability
Unique encapsulation of the TiO2particle by a continuous coating of silica (SiO2) is responsible for the excellent durability of Titanium dioxide R-706 . Florida exposure data for Titanium dioxide R-706 shows excellent gloss retention and chalk resistance.
Excellent Dispersibility
The alumina ((Al2O3) surface treatment reduces the contact between TiO2particles, resulting in excellent dispersion of Titanium dioxide R-706 in solventborne systems. To further enhance dispersion, we apply anorganic treatment during manufacture.
Easy Wet-in
Novel precipitation of the silica and alumina surface treatments result in the low oil absorption properties of Titanium dioxide R-706 that are responsible for its excellent wet-in. Less power required for Titanium dioxide R-706 wet-in could result in productivitygains and capacity increases.
Good Hiding
The low surface treatment levels, 3% amorphous silica and 2.5% alumina, result in a high TiO2content for Titanium dioxide R-706 , contributing to good hiding. The mean particle size of Titanium dioxide R-706 approaches the optimum particle size for scattering efficiency.
Blue Undertone
Small particle size TiO2grades scatter blue light more effectively than larger particle size grades and hence have a bluer undertone. The bluer undertone of Titanium dioxide R-706 imparts a brighter, cleaner tint.
Product Storage
The shelf life of Titanium dioxide R-706 is indefinite as long as the material is kept from direct contact with moisture. For further information about this grade or to request a sample, please see the Ti-Pure web site.
