R1930 rutile-type titanium white pigment is a universal multi-purpose titanium white pigment. Its surface is coated with dense inorganic zirconium and aluminum layers and undergoes special organic treatment. The product design aims to approach the quality standards of similar products from abroad produced by the chlorination method.
R1930 features high whiteness, high gloss, a bluish base tone, fine particle size with a narrow distribution, high ultraviolet absorption capacity, excellent outdoor weather resistance, strong anti-frosting ability, strong covering power and color removal ability, good dispersion and stability. The products made with it have bright colors and high glossiness.
R1930 is a high-grade, general-purpose multi-purpose rutile-type titanium dioxide powder. It is widely used in various indoor and outdoor architectural coatings, industrial coatings, powder coatings, as well as plastic color granules, plastic profiles, rubber, high-grade inks and paper-making fields.
This product is safe and comes in a white powder form. During transportation, it should be protected from moisture. When storing, it should be placed in a cool, ventilated and dry place.
When handling, avoid inhaling dust. If contaminated, it can be cleaned with soap and water. For specific instructions, please refer to the corresponding material safety data sheet.
Packaging: 25kg bag

Improve dispersion and binder choice: pre-wet R1930 with a dispersant, use a high-energy bead mill, and optimize pigment volume concentration (PVC). These steps often let formulators reduce pigment 5–15% while maintaining opacity — validate with a small-scale lab panel.
For paints and high-gloss inks: start with a high-shear pre-dispersion (rotor-stator) at ~20–35% solids, then finish with a wet bead mill using 0.3–0.6 mm beads until target grind (Hegman 7–8 for many coatings). Keep mill temperature controlled (<40–45°C) and avoid over-dispersion. Use a non-ionic or polyacrylate dispersant at recommended dosages (0.2–0.6% on pigment) and add defoamer only after grind to preserve gloss.
R1930 can support sustainability by enabling formulation efficiency (reducing pigment use through higher hiding), improving durability (fewer repaints) and lowering VOC burden (lower oil absorption can reduce solvent/coalescent needs). For formal claims, request supplier LCA or emissions data and run a cradle-to-gate comparison for your product.
