NATURAL AMORPHOUS SILICA (SUB-MICRON GRADE)

Natural Amorphous Silica (Sub-Micron Grade)

Overview

A 100% natural, fossil-origin functional mineral engineered for premium surface performance and high thermal stability. Milled to a controlled sub-micron particle size without any chemical modification, this ultra-pure grade delivers outstanding clear-coat matting efficiency and mechanical reinforcement with a zero-carbon-compromise profile.

Key Technical Specifications

• Chemical Purity: 99.20% – 99.70% SiO ₂
• Particle Size (Zeta Dimension): 546.8 nm
• Heavy Metal Profile: Ultra-low iron (Fe ₂ O ₃ ≤ 0.030%) and chromium (Cr ₂ O ₃ ≤ 0.00040%)
