Industry Grade Anatase Titanium Dioxide PDA2000 - High-Performance TiO2 for Coatings and Plastics

PDA series anatase titanium dioxide has extremely low heavy metal content and is suitable for coating, plastic, rubber and other purposes, and is also an excellent chemical base material for making fiber and paper.

PDA2000 is a kind of anatase titanium dioxide pigment produced by sulfuric acid method.Its hydrolysis and calcination are specially controlled and designed. 

It uses acid-soluble high-titanium slag as raw material. It is a high-grade anatase titanium dioxide. Its dispersion and coverage are higher than that of PDA1000 titanium dioxide. It has the characteristics of low oil absorption, uniform fineness and excellent whiteness.

Basic Information

Classification: It belongs to the anatase type and meets the classification standards of ISO 591 - 1:2000 (A1) and ASTM D - 478:84 (1).
CAS Number: 13463 - 67 - 7.
Appearance: It is a white powder with a density of 3.7 g/cm³.

Technical Specifications

High Purity: The TiO₂ content is not less than 98%, ensuring its excellent performance in coloring, hiding power, and durability.

Good Dispersion: It has good dispersion properties, which can be evenly distributed in coatings and plastics matrices to prevent agglomeration and ensure the uniform color and performance of the final products.

Excellent Color Characteristics: The tint strength (compared with the standard sample) is ≥ 108% * 100. In terms of color, L * sample/L * standard ≥ 92.30, and |△b| ≤ 0.5, which can provide coatings and plastics with good whiteness and a blue - based hue, enhancing their decorative effect.

Other Properties: The pH value of the water suspension is 6.8 - 8.5, the oil absorption is ≤ 20 g/100g, the hiding efficiency is ≥ 100%, the residue (45 - µm sieve pore) is ≤ 0.03% (m/m), the water - soluble matter content is ≤ 0.6% (m/m), and the dispersion in water is ≥ 80%.

Performance Advantages

Good Hiding Power: It can effectively cover the substrate, allowing coatings and plastics to have a pure and uniform color, even if the underlying material has a different color.

Low Oil Absorption: The low - oil - absorption property helps reduce the amount of resin or other binders required in coatings and plastics, thereby reducing production costs. At the same time, it also helps to improve the surface properties of the final product, such as gloss and smoothness.

Even Particle Size Distribution: The uniform particle size distribution is beneficial to improving the dispersion stability of the product in coatings and plastics and enhancing the mechanical properties and appearance quality of the final product.

Plastics: It is widely used in plastics such as PVC pipes and master - batches. It can improve the whiteness and color stability of plastics, and at the same time, enhance their resistance to ultraviolet rays, heat resistance, and mechanical properties, prolonging the service life of plastic products.

Packaging and Storage

Usually, PDA2000 is packaged in 25 - kg bags or 1000 - kg net - weight containers. It should be stored in a clean and dry indoor environment to prevent moisture absorption and contamination, which may affect its performance.

Application: widely used in paper, plastic, rubber, ink, paint and other industries.

Coatings: It is suitable for various coatings such as interior wall coatings and industrial coatings. It can improve the whiteness, hiding power, and weather resistance of coatings, making the coated surface look white, bright, and durable. It also helps to enhance the adhesion of coatings and prevent paint sagging.
