Product Detail
Technical index

Product Name: Silica-Alumina Modified Barium Sulfate (BaSO4)

Properties: Apperance with white powder, this is a composite inorganic powder material formed by coating one or more layers of silica (SiO2) and alumina (Al2O3) on the surface of ordinary precipitated barium sulfate through a special process. It exhibits excellent dispersibility, glossiness, and strong weather resistance.


Packaging: 25 kg/bag, with the inner bag made of polyethylene plastic film with a drawstring closure, and the outer bag made of polypropylene woven plastic with machine-stitched seams; or multilayer paper bags with machine-stitched seams. Custom packaging is also available according to user requirements.


Precautions: Protect from exposure to sunlight and rain; store in a dry and ventilated warehouse with a base layer to prevent moisture; do not store or transport with colored items to avoid contamination; prevent packaging damage during loading and unloading.


Applications: Due to the special inorganic coating treatment, it can be used in automotive topcoat, metallic paint, repair paint, and electronic ink, and is also widely applicable in outdoor coating, high-end paint, and other industries.
