confers good exterior durability on coatings Chloride Process Titanium Dioxide pigments

1. Rutile type chloride process titanium dioxide R920 is a multi-purpose grade pigment

recommended for use when a single pigment is required to perform well in interior and exterior

gloss and semi-gloss systems. Though less resistant to weathering than other grades, R-920

provides an excellent balance of performance properties.

A rutile titanium dioxide pigment, R-920 is manufactured by the chloride process and is supplied

as a fine, dry powder. It is specifically formulated to perform well in a wide range of solvent-based

and aqueous systems and provides:

 develops higher hiding power and tinting strength at high pigment volume concentrations than rutile pigments with lower inorganic surface

 imparts a neutral tone and high brightness to coatings

 improves the brightness and opacity of paper coatings

 disperses readily

 confers good exterior durability on coatings

 has a higher water and dispersant demand than standard grades

2. Applications where Rutile type chloride process titanium dioxide R920 is of particular value are:

• Industrial maintenance, implement, and transportation finishes
• Container coatings
• Architectural interior flat, semi-gloss and exterior finishes
• Exterior industrial finishes except those requiring the highest level of durability
• Powder coatings

Description:

1. Improved Hiding Power

• Better coating coverage
• Minimum TiO2 use in coatings formulas

LiangJiang Brand Tio2 R-920 provides exceptional hiding power and tint strength in a wide variety of coating formulations. 

As shown in Figure 2, our extensive testing has shown that LiangJiang Brand Tio2 R-920 consistently outperforms multi-purpose grades from global competitors.

The exceptional dispersion and unique particle size distribution of LiangJiang Brand Tio2

 R-920 is the key to excellent optical performance. Using LiangJiang Brand Tio2 R-920 will provide excellent coating coverage and may allow coating producers to reduce your 

coating raw material costs by reducing the amount of TiO2 in the paint.

Superior Dispersion

• Lower energy consumption
• Higher productivity from shorter dispersion times
• Improved product quality consistency from more consistent dispersion

• Liangjiang Brand R920 also provides
  • Superior tinting strength
  • Excellent whiteness and brightness

Figure 3 demonstrates the alkyd ease of dispersion

advantage of Liangjiang Brand R920 relative to competitive grades. It also highlights the opportunity for productivity 

improvements and energy savings from using Liangjiang Brand R920

As alkyd dispersion time and intensity are increased the dispersion condition is evaluated 

using a special hegman gauge. Dispersion condition is analyzed using the Liangjiang Brand Dispersion Optical Counter (DOC) which takes a digital image of the drawdown and 

uses proprietary protocol to measure the number of undispersed particles.

The results show wide variation in how different TiO2 grades disperse following the various 

grind conditions. While most pigments require the highest grind intensity (5 minutes at 12 m/s) 

to achieve

a clean dispersion (<10 undispered particles), Liangjiang Brand R920 achieves a clean dispersion with much less time and energy.
