GBASEA Natural Barium Sulfate Extinction B125 for Industrial Coatings
Product Overview
GBASEA Natural Barium Sulfate Extinction B125 is a high-purity, micronized natural barium sulfate extender engineered to optimize opacity, rheology, and durability in demanding industrial coating systems. Sourced from premium baryte ore and refined through a zero-waste process, B125 delivers 20–30% higher hiding power compared to conventional calcium carbonate or talc, enabling formulators to reduce TiO2 usage by 15–25% while maintaining film integrity and gloss uniformity.
With a controlled particle size distribution (D50: 1.5–2.5 µm) and ultra-low oil absorption (16–20 g/100g), B125 excels in solvent-borne, waterborne, and powder coatings, offering multifunctional benefits:
- TiO2 Extender: Maximizes pigment spacing efficiency for enhanced light scattering.
- Chemical Shield: Inert barrier against acids, alkalis, and salt spray (ASTM B117).
- Rheology Modifier: Pseudoplastic flow for sag resistance and sprayability in high-build coatings.
- Matting Agent: Achieves semi-gloss to matte finishes (60° gloss: 10–30 GU).
Certified under REACH, RoHS, and ISO 14001, B125 aligns with circular economy principles, offering a sustainable alternative to synthetic extenders with a 50% lower carbon footprint than precipitated barium sulfate.
Key Features & Competitive Advantages
Unmatched Opacity & Cost Efficiency
- High Refractive Index (1.64): Bridges the gap between binders (1.5) and TiO2 (2.7) for optimal light diffusion.
- TiO2 Reduction: Slashes titanium dioxide consumption by 15–25% without compromising contrast ratio (ISO 6504-1: ≥95%).
- Low Oil Absorption (16–20 g/100g): Minimizes resin demand, reducing formulation costs by up to 18%.
Superior Processing & Durability
- Thermal Stability (1,600°C): No decomposition in powder coatings or high-temperature automotive systems.
- Chemical Inertness (pH 2–12): Resists acidic rain, alkaline cleaners, and marine corrosion.
- Abrasion Resistance: 25% improvement in scrub resistance (ASTM D2486) and pencil hardness (H–2H).
Eco-Certified & Sustainable
- Natural Sourcing: Mined from low-heavy-metal baryte deposits (≤10 ppm Pb/Cd/As).
- Closed-Loop Production: 90% process water recycling and 70% renewable energy usage.
- Dust-Free Granules: OSHA-compliant handling with ≤0.2% respirable particles.
Multifunctional Versatility
- Compatible with epoxy, polyurethane, acrylic, and silicone-modified resins.
- Enhances conductivity control in E-coat primers and anti-static floor coatings.
