High Purity Natural Barium Sulfate Used for Coating TX-2HB - Natural Barium Sulfate for High-Performance Coating Applications
Features:
1.Narrow and even distribution in size, excellent glossy retention, similiar refractive index ax organic resins.
2.Low oil absorption, good leveling property.
3.High sluggishness and purity,chemical resistance, excellent salt and weather resistance.
Product Characteristics
High Purity: The content of barium sulfate is as high as 90% - 99%, with extremely low impurity content.
High purity can ensure the chemical stability of barium sulfate and the consistency of its physical properties, avoid the adverse effects of impurities on the performance of coatings, and improve the stability and reliability of high - performance coatings.
Excellent Chemical Stability: It has strong chemical stability and is chemically inert. It is resistant to acids and alkalis and hardly reacts with other substances in the coating.
It can maintain stable performance in different chemical environments, which is beneficial for the long - term use of coatings in harsh environments and improves the weather resistance of coatings.
Good Dispersion: Through special surface treatment, TX - 2HB has good dispersion in coating systems. It can be evenly distributed in the coating without agglomeration, and has a high affinity with resin - based materials. This can improve the leveling property of the coating, make the coating film smoother, and enhance the decorative and protective properties of the coating.
High Whiteness: It has a high whiteness, usually reaching 88% - 96% or even higher. In coatings, it can play a role in whitening and color - adjustment, helping to improve the hiding power and decorative effect of coatings, and making the color of the coating film more pure and bright.
Application in Coatings
Improving Hiding Power: As an important extender pigment in coatings, high - purity natural barium sulfate TX - 2HB can effectively cover the surface of the object to be coated.
It can be evenly distributed in the coating film to form a dense structure, blocking the light from penetrating the coating film, thereby improving the hiding power of the coating and reducing the amount of titanium dioxide used, which helps to reduce costs.
Enhancing Weather Resistance: Due to its chemical stability and good dispersion, the coating added with TX - 2HB has better weather resistance.
It can resist the erosion of ultraviolet rays, moisture, acids and alkalis, and other environmental factors, prevent the coating from aging and fading, and maintain the appearance and performance of the coating, suitable for outdoor coatings and other applications with high weather resistance requirements.
Improving Gloss and Decorative Properties: The fine particle size and good dispersion of TX - 2HB can fill the gaps in the coating film, making the surface of the coating film smoother and more glossy.
In some coatings with high requirements for gloss and decoration, such as automotive coatings, furniture coatings, and architectural decorative coatings, the addition of TX - 2HB can significantly improve the decorative properties of the coating, making the coated object more beautiful.
