The product has good dispersion properties, thixotropic properties, and transparency. Suitable for light-curing coatings, it improves printability, reduces fogging and high levels of filling, and is halogen-free. An ultrafine barium sulfate product subjected to wet high temperature surface treatment using inorganic materials. The wet high-temperature coating process makes the barium sulfate particles have good dispersing properties, and has excellent steric hindrance in other pigment components, and utilizes the interaction of different charges on the surface of the particles of other particles of the particles to effectively isolate the agglomeration of the pigment particles. The degree of opacity of each pigment component is utilized to reduce the amount of pigment used and further optimize the cost structure. The hydrated oxide formed by the inorganic coating can facilitate the reaction with the acidic functional group of the organic substance, is adsorbed on the surface of the barium sulfate particle in the alkyd resin, and dissociates into the electric double layer in the presence of a small amount of water, so that the barium sulfate particle band is intact. Positive charge, adsorbing a layer of resin on the surface, due to the protection and wetting of the resin layer, the dispersion of barium sulfate particles becomes extremely strong; at the same time, the inorganic oxide coating component forms a protective layer on the surface of barium sulfate. It also reflects light to the greatest extent, which increases the gloss of the coating and supports a near-perfect color development.
