GBASEA Barium Sulfate Precipitated 3000 Mesh for Powder Coating Applications
Product Overview
GBASEA Barium Sulfate Precipitated 3000 Mesh is a premium-grade, synthetic inorganic filler engineered to elevate the performance of powder coatings across industries. With an ultra-fine particle size of 3–5 μm (D97 ≤5 μm) and a purity level exceeding 99%, this barium sulfate grade delivers exceptional dispersion, gloss enhancement, and corrosion resistance in epoxy, polyester, and hybrid coating systems. Ideal for automotive, architectural, and industrial applications, GBASEA’s barium sulfate improves surface smoothness, UV stability, and adhesion while reducing material costs and environmental impact.
Processed via advanced precipitation and micronization technologies, this 3000-mesh barium sulfate is free from heavy metals, chlorides, and soluble salts, ensuring compliance with REACH, RoHS, and FDA standards. Its low oil absorption (≤15 g/100g) and high refractive index (1.64) make it indispensable for high-gloss finishes, while its thermal stability (up to 1,580°C) supports high-temperature curing processes. Trusted by leading coating manufacturers, GBASEA Barium Sulfate empowers formulators to achieve superior opacity, scratch resistance, and weatherability in powder coatings for demanding environments.
Key Features & Advantages
Ultra-Fine Particle Size & Uniform Dispersion

Production Process
GBASEA Barium Sulfate 3000 Mesh is synthesized through a meticulously controlled 7-stage process:
- Raw Material Selection: High-purity barite ore and sulfuric acid are sourced from ISO-certified suppliers.
- Precipitation Reaction: Barite reacts with sulfuric acid under pH-controlled conditions to form BaSO₄ slurry.
- Washing & Filtration: Impurities (Fe²⁺, Cl⁻) are removed via multi-stage membrane filtration.
- Surface Modification: Silane or stearic acid treatment improves compatibility with resin systems.
- Micronization: Jet milling reduces particles to 3–5 μm with narrow size distribution.
- Drying: Spray drying at 120°C ensures moisture content ≤0.2%.
- Quality Assurance: Each batch undergoes SEM-EDS, XRD, and coating adhesion testing.
Formulation Guidelines
- Recommended Dosage: 5–25% by weight, depending on coating type and desired properties.
- Mixing: Pre-disperse in resin blends using high-speed dispersers (1,500–2,000 rpm) for 20–30 minutes.
- Compatibility: Suitable with epoxy, polyurethane, and acrylic resins; test with silicone additives for mar resistance.
- Curing: Optimize oven temperatures (140–200°C) to match resin crosslinking requirements.
Packaging & Storage
- Packaging: 25 kg multi-layer kraft paper bags with polyethylene liners; 500 kg FIBCs available.
- Storage: Keep in a dry, cool (<25°C) environment away from moisture; shelf life 24 months.
