GBASEA Natural Barium Sulfate Extinction B100 for High-Gloss Coatings
Product Overview
GBASEA Natural Barium Sulfate Extinction B100 is a micronized, high-purity natural barium sulfate extender engineered to deliver unparalleled surface smoothness, gloss enhancement, and durability in high-performance industrial coatings. Mined from premium baryte ore and refined through a zero-waste, eco-certified process, B100 optimizes light reflection and film integrity, enabling 15–20% higher 60° gloss retention compared to conventional extenders like calcium carbonate or precipitated barium sulfate. With a tightly controlled particle size distribution (D50: 0.5–1.0 µm) and ultra-low oil absorption (12–16 g/100g), this extender achieves flawless flow-out in high-gloss automotive, appliance, and marine coatings while reducing TiO2 consumption by 10–18% through advanced pigment spacing.
Certified under REACH, RoHS, and ISO 14001, B100 is the sustainable choice for formulators seeking to balance premium aesthetics with environmental compliance. Its inert chemistry and exceptional dispersion stability make it ideal for solvent-borne, waterborne, and UV-curable systems requiring mirror-like finishes and long-term resistance to weathering, abrasion, and chemical exposure.
Key Features & Competitive Advantages
Gloss Enhancement & Surface Perfection
- Optical Uniformity: Minimizes micro-texture defects (orange peel) via monodisperse particle distribution (PDI <0.2).
- 60° Gloss Retention: Achieves 90–100 GU in topcoats, outperforming talc or silica extenders by 25–30%.
- TiO2 Synergy: Aligns refractive index (1.64) with TiO2 (2.7) to maximize light scattering efficiency.
Processing Efficiency & Cost Savings
- Ultra-Low Oil Absorption (12–16 g/100g): Reduces resin demand by 15–20%, lowering formulation costs.
- Shear-Thinning Rheology: Prevents sagging in vertical applications without compromising sprayability.
- Dispersion Stability: 95% Hegman grind gauge readings even after 72-hour storage (ASTM D1210).
Extreme Durability
- Chemical Resistance (pH 1–14): Withstands sulfuric acid, caustic soda, and marine salt spray (ASTM B117).
- Abrasion Resistance: 30% improvement in Taber abrasion (ASTM D4060) and pencil hardness (2H–3H).
- Thermal Stability (1,500°C): Zero decomposition in powder coatings or high-bake automotive systems.
Sustainability & Compliance
- Natural Sourcing: Low heavy-metal baryte ore (≤5 ppm Pb/Cd/As) with 90% closed-loop water recycling.
- Carbon Footprint: 0.6 kg CO₂/kg (70% lower than synthetic barium sulfate).
- Dust-Free Handling: OSHA-compliant granules with ≤0.1% respirable particles.
