Overview
Coating quartz powder is a high-purity, finely ground silica product derived from natural quartz. It is widely used as a functional filler in industrial applications due to its hardness, chemical inertness, and thermal stability. This material enhances the durability and performance of coatings by improving scratch resistance, UV stability, and mechanical strength. Its consistent particle size distribution ensures uniform dispersion in liquid formulations.
Physical and Chemical Properties
Coating quartz powder exhibits a Mohs hardness of 7, making it highly resistant to abrasion. Its low thermal expansion coefficient (5.5×10−7/°C) minimizes cracking in temperature fluctuations. The material is chemically inert to acids (except hydrofluoric acid) and alkalis, ensuring compatibility with most binder systems. Particle sizes typically range from 200 to 2,500 mesh, with finer grades offering smoother surface finishes.
Main Applications
In architectural paints, quartz powder improves weather resistance and reduces chalking. Industrial coatings benefit from its anti-corrosive properties in marine and chemical environments. The construction sector utilizes it in epoxy floorings and cementitious overlays for enhanced wear resistance. Specialty applications include silicone rubber reinforcement and ceramic glaze formulations where thermal shock resistance is critical.
Safety and Storage
Respirable crystalline silica (RCS) poses occupational hazards; OSHA mandates exposure limits below 50 μg/m³ (8-hour TWA). Use NIOSH-approved N95 respirators during handling. Store in moisture-proof packaging on pallets to prevent caking. Bulk storage silos should incorporate dust collection systems. In case of spillage, avoid dry sweeping—use HEPA-filter vacuums or wet cleaning methods.
B2B Procurement Guide
Key specifications to evaluate include SiO2 content (≥99.5% for premium grades), iron oxide impurities (<0.01% for whiteness), and moisture content (<0.5%). Request test reports for oil absorption value (typically 22-28 g/100g) and pH stability (6.5-7.5). For large orders, negotiate FOB pricing with moisture-resistant big bag packaging (500-1,000 kg) to reduce logistics costs.
