High-purity precipitated barium sulfate with exceptional whiteness (CIE L* ≥ 98.5) and low chroma.
Narrow particle size distribution (D50 ≈ 0.7–0.9 µm) ensuring excellent dispersion stability in demanding formulations.
Low soluble salt content (< 0.15% as Na₂SO₄) and minimal heavy metals, supporting compliance with stringent regulatory requirements.
Optimized surface treatment for improved compatibility with organic binders in coatings, inks, and plastics.
Consistent batch-to-batch performance, validated through rigorous QC protocols per ISO 9001 standards.
High-gloss automotive basecoats and clearcoats requiring superior opacity and scratch resistance.
Pigment extenders in premium architectural and industrial waterborne and solventborne coatings.
Functional filler in engineering plastics (e.g., polypropylene, ABS) for dimensional stability and surface finish enhancement.
Key component in specialty printing inks—especially gravure and flexographic inks—for improved print definition and ink rheology control.
Filler in high-clarity polymer films and masterbatches where low haze and UV stability are critical.
