Common questions about Barytes & PPT BaSO₄ in paints & coatings applications
PPT (precipitated) BaSO₄ has ultra-high purity (>99%), D50 < 1 µm, and acts as a premium TiO₂ spacer and gloss enhancer. Natural BaSO₄ (barytes) provides cost-effective high-density filler loading with good mechanical reinforcement and chemical resistance.
PPT BaSO₄ has a refractive index (1.63–1.65) closely matching common powder resins, making it nearly transparent in the binder vehicle while physically separating TiO₂ particles to prevent agglomeration and maximize light scattering efficiency per unit of TiO₂.
No — BaSO₄'s chemical inertness and stable rheology ensure consistent viscosity and melt flow during extrusion, good powder fluidization, and reliable press performance without reactivity toward resins or curing agents.
Yes — PPT BaSO₄'s matched refractive index enables it to become transparent in the resin matrix, making it ideal for thin-film powder coatings, clear coats, and transparent matte systems where whiteness must be minimized.
BaSO₄ improves film build uniformity, abrasion resistance, and chemical durability. Its Mohs hardness (~3) contributes surface durability without excessive abrasion of extrusion equipment, and its high density supports stable film formation across all tested mechanical parameters.
