Product Characteristics
High Purity: It usually has a high barium sulfate content, generally reaching over 95%, with low impurity content. High purity ensures the chemical stability of barium sulfate and the consistency of its physical properties, which is beneficial for maintaining the performance stability of coatings and reducing the adverse effects of impurities on coating quality.
Fine Particle Size: The particle size of TX - 812 is relatively fine, usually in the range of 1 - 10 microns, and the particle size distribution is narrow. This enables it to be evenly distributed in coatings, filling the gaps in the coating film, which is conducive to improving the smoothness and gloss of the coating surface.
Excellent Gloss: It has excellent optical properties, which can significantly improve the gloss of coatings. The high - gloss effect can make the coating surface present a bright and smooth appearance, enhancing the decorative effect of the coating and being suitable for applications with high - gloss requirements, such as high - end furniture coatings and automotive top - coats.
Good Chemical Stability: It is chemically inert, resistant to acids, alkalis, and other chemical substances, and hardly reacts with other components in the coating. It can maintain stable performance in different chemical environments, improve the weather resistance of coatings, and is suitable for use in various harsh environments.
Good Dispersion: Through surface treatment, TX - 812 has good dispersion in coating systems. It can be well - dispersed in the coating without agglomeration, has a high affinity with resin - based materials, and can improve the leveling property of coatings, making the coating film more uniform and dense.
Application in Coatings
Improving Gloss and Decorative Properties: The addition of TX - 812 can significantly improve the gloss of coatings, making the coating surface bright and shiny, thereby enhancing the decorative properties of coatings. It is widely used in high - end decorative coatings to meet the requirements for a beautiful and luxurious appearance.
Enhancing Hiding Power: It can cooperate with titanium dioxide and other pigments to improve the hiding power of coatings.
By filling the gaps between pigment particles, it makes the pigment distribution more uniform, reduces the light transmittance of the coating film, and improves the ability of the coating to cover the substrate, which helps to reduce the amount of titanium dioxide used and reduce costs.
Improving Weather Resistance: Due to its chemical stability and good dispersion, it can enhance the resistance of coatings to ultraviolet rays, moisture, acids, alkalis, and other environmental factors, prevent the coating from aging, fading, and cracking, and prolong the service life of the coating. It is suitable for outdoor coatings and other applications with high weather resistance requirements.
Improving Coating Performance: It can improve the physical and mechanical properties of coatings, such as hardness, abrasion resistance, and impact resistance. The fine particles of barium sulfate can fill the microstructure of the coating, improve the compactness of the coating film, and enhance the overall performance of the coating.
