High-Gloss Powder Coatings: Why Choose XT-308 Ultrafine Barium Sulfate?
In powder coatings, especially high-gloss applications, the whiteness, gloss, specific gravity, and stability of fillers significantly impact the final appearance and formulation.
XT-308 Natural Ultrafine Barium Sulfate is refined from natural high-purity ultrafine barite ore. Manufactured under SPC quality control without pickling reactions, it is widely used in various high-gloss powder coatings.
Why Focus on XT-308 for High-Gloss Powder Coatings?
XT-308 features high whiteness, high gloss, high specific gravity, acid and alkali resistance, strong chemical inertness, excellent stability, moderate hardness, and the ability to absorb harmful radiation.
For high-gloss powder coatings, product whiteness and gloss are crucial references during formulation evaluation. At the same time, its strong chemical inertness and stability make it highly adaptable to various application systems.
