Product name: Titanium Dioxide Additive AY-726W+
AY-726W+ is a new achievement of Onmillion Group researched and developed by many scientific research institutions and it takes high-tech nanotechnology. The product takes barium sulfate as  core with the titanium dioxide wrapped. And then it has been coated with compact silica. It has even particle size, narrow distribution scope, good chemical stability, high activation grade, good dispersity and high whiteness etc. It can be specially used in products such as various powder coating, plastics, oil paint, ink, etc. As to replace various white pigments, it obviously improve surface gloss, weatherability of products and reduce cost.

Product characteristics
Good hiding power, good dispersity and can be used to replace 20% titanium dioxide powder in formula without impact on its hiding power.

Acid resistant, alkali resistant, high temperature resistant without gloss loses, and it also has good salt fog resistance and weatherability features. 

High activation grade and good compatibility with various resins, and it can significantly enhance various mechanical properties of products. High whiteness and neutral color, and it can keep color stable and reduce consumption of pigments.
High value and there are high gloss and vividness on surface of products.

Little impurity and no harmful substance which can guarantee safety of products and cleanness on surface of coating. 

Product use
AY-726W+ can be widely used in various coatings, paint, plastic, paper-making and printing oil industries etc and can reduce consumption of white pigment.

Packaging and storage
Generally 25kg/bag. Store in a cool, dry, dark place and avoid moisture.
