Chemours Ti Pure R-931

Products Information of Chemours Ti Pure R-931

Rutile titanium dioxide can provide maximum protection for extended outdoor service life. However, not all grades of TiO2 are created equal. For durable polyolefin applications, Ti-Pure™ R-931 has the perfect combination of weatherability, optics, and processibil ity to meet the most exacting requirements.

Chemours Ti Pure R-931 titanium dioxide has been specifically designed to achieve:

• Maximum weather resistance

• Bright, neutral whites

• Color formulation flexibility

• Superior processibil ity

Exceptional Durability

• UV energy is absorbed and dissipated by the fine sized particles. Innovative silica encapsulation technology is used to impart a chemically inert coating on  each TiO2  particle to prevent microcracks, chalking, or other degradation of the plastic.

• It improves the efficiency of UV stabilizers.

• High gloss retention — polyolefin parts look and perform like new, longer.

Pin-point Color

• With the unique combination of a neutral undertone, excellent opacity, and strong brightness, It is the easy solution for matching color tints or delivering bright, clean whites.

Low Volatility

• At elevated temperatures, general grades of titanium dioxide can “de-volatil ize,” creating downstream quality issues like holes or other imperfections, particularly in thin film applications. To compensate, most users end up slowing down their process.

• Resists “lacing” or “de-volatilization” and in the process, allows users to run faster.

Excellent Dispersibility

• Flows easily and disperses readily into a variety of resins, insuring consistently and reliably, high quality products.

• Its optimized surface chemistry enhances bulk flow and improves processing.

Chemours Ti Pure R-931 – Frequently Asked Questions (FAQ)

Q1: What is the primary function of Ti Pure R-931 in coatings and plastics formulations?

A: Ti Pure R-931 is a high-performance rutile titanium dioxide pigment engineered to deliver exceptional brightness, opacity, and durability. It is widely used to enhance hiding power, whiteness, and UV resistance in architectural coatings, industrial finishes, and engineering plastics.

Q2: How does R-931 differ from other TiO₂ grades in terms of surface treatment and dispersion stability?

A: R-931 features a proprietary dual-surface treatment combining alumina and silica, optimized for excellent dispersibility in both water-based and solvent-based systems. This treatment contributes to improved gloss retention, reduced flocculation, and enhanced compatibility with common resin systems.

Q3: Is Ti Pure R-931 suitable for use in exterior applications requiring long-term weather resistance?

A: Yes — R-931 is specifically designed for demanding exterior applications. Its robust surface chemistry and crystalline structure provide superior resistance to chalking, gloss loss, and color shift under prolonged UV exposure and environmental stress.

Q4: What are typical dosage guidelines when incorporating R-931 into paint or plastic formulations?

A: Dosage depends on the required opacity, film thickness, and end-use performance targets. In most architectural paints, it is typically used at low concentrations relative to total solids, generally ranging from 0.1% to 2% by weight — though optimal loading should be determined through formulation testing.
