Detailed Information
R-2196 is a rutile titanium dioxide pigment designed for solvent-based coating systems where both opacity and surface appearance must be strong. According to the product page, it is characterized by high gloss, high whiteness with a blue undertone, and easy wetting and dispersing. That combination is useful when you want a bright, crisp white and a smooth film that holds gloss after drying or baking, rather than a finish that looks hazy or dull. In tinted systems, a cleaner undertone can also help pastels and light colors read as more “pure,” because the base white contributes less unwanted warmth.
The suggested applications are furniture coatings and other industrial solvent-borne paints that require high color performance. In these systems, dispersion quality is often the difference between a premium look and a problem batch. A practical process is to pre-wet the powder with your resin/solvent blend (and a compatible dispersant), add pigment under controlled shear, and then grind or mill until you reach the fineness needed for your gloss target. Good wetting helps shorten milling time, while stable dispersion helps reduce issues such as flooding/floating, seediness, and gloss loss during storage. As with any white pigment, clean handling is important: prevent moisture pickup, avoid iron contamination, and keep packaging sealed to maintain consistent viscosity and shade.
The technical properties listed on the page support this positioning. TiO2 is 94% with zirconia/alumina (ZrO2/Al2O3) inorganic surface treatment and organic surface treatment. ISO 591-1 classification is R2 and the stated color difference control is Delta E ≤ 0.5. Relative scattering force is 95–105% and density is 4.0 g/cm3. Dispersion in a polyester system is reported as ≤ 27.5 um, with CIE L* 95.3 and reducing power (TCS) 1950. Processing-related indicators include pH 7.0, oil absorption 19 g/100 g, residue on 45 um 0.01%, resistivity 100 ohm·m, and volatiles at 105°C at packaging 0.3%. Together, these values indicate a controlled, appearance-oriented rutile grade intended for consistent, glossy solvent-borne coating production.
