GBASEA Natural High Gloss Barium Sulfate B800 for Paints and Plastics
Product Overview
GBASEA Natural High Gloss Barium Sulfate B800 is a premium-grade, naturally sourced mineral filler engineered to deliver exceptional gloss, durability, and process efficiency in coatings, plastics, and specialty applications. With a precisely controlled particle size distribution (D97 ≤1.8 µm) and a purity level exceeding 99.5%, this ultra-fine barium sulfate enhances surface smoothness, light reflectivity, and mechanical strength while maintaining outstanding compatibility with polar and non-polar matrices. Ideal for high-gloss automotive paints, premium packaging plastics, and eco-conscious formulations, GBASEA B800 combines the benefits of natural mineral refinement with advanced surface modification to address critical challenges in opacity, cost reduction, and environmental compliance.
Processed via a proprietary dry-milling and organic treatment process, GBASEA B800 minimizes resin demand, reduces VOC emissions, and improves dispersion stability in solvent-based, waterborne, and UV-curable systems. Its low oil absorption (≤12 g/100g) and high refractive index (1.64) make it a sustainable alternative to titanium dioxide (TiO₂), while its halogen-free, REACH-compliant profile ensures alignment with global regulatory standards. Trusted by leading manufacturers in automotive, construction, and consumer goods industries, GBASEA B800 empowers formulators to achieve mirror-like finishes, extended product lifespans, and reduced carbon footprints without compromising performance.
Key Features & Advantages
Unmatched Surface Aesthetics
- High Refractive Index (1.64): Maximizes light reflection and opacity for automotive topcoats, luxury packaging, and electronic housings.
