3M Ceramic Microspheres W-210 High-Whiteness Ultra-Fine Solid Ceramic Microspheres for Coatings & Inks

Full Name & Product Positioning Product Full Name: 3M W-210 High-Whiteness Ultra-Fine Solid Ceramic Microspheres A white solid ceramic microsphere grade made of alkali aluminosilicate ceramic, with whiteness L value of 95 or above, particle size D50 approx. 3 μm and D90 approx. 12 μm, with fine and uniform particles. Commonly used for high-filling wear-resistant modification of coatings and inks, suitable for low-VOC environmentally friendly formulations. Used as a wear-resistant hardening filler for industrial maintenance paints, wear-resistant coatings, and ink systems, improving coating scrub resistance, abrasion resistance, and scratch resistance. Core Technical Parameters   True Density 2.4 g/cm³   Bulk Density 1.5 g/cm³   Mohs Hardness Grade 6   Compressive Strength >60,000 psi (>4,200 kg/cm²)   Particle Size D10 1 μm, D50: 3 μm, D90: 12 μm   Whiteness (L value) ≥95 Softening Point 1020°C pH Value 9.0-12.0 (5% aqueous solution) Refractive Index 1.53 Standard Packaging  22.68 kg/bag Physical Form: High-whiteness ultra-fine solid white powder Key Advantages ·   Good hardness and compressive performance, can improve scrub resistance, abrasion resistance, and scratch resistance of coatings and inks, addressing film wear, powder shedding, and gloss loss. ·   High powder whiteness (L value ≥95) and ultra-fine uniform particles result in uniform coating color after filling, with minimal impact on the decorative effect of the coating base color. ·   Controlled particle size distribution with low resin adsorption allows high filler loading, optimizes formulation systems, and is suitable for low-VOC environmentally friendly coating production. ·   Heat resistant, corrosion resistant, aging resistant, and UV resistant; outdoor use can delay powdering, fading, and cracking. ·   Spherical particles have good flowability and dispersibility, improving coating workability and film smoothness, reducing production defects. Main Application Areas Core Applications: Industrial maintenance paints, wear-resistant industrial coatings, high-filling coating systems, ink wear-resistant modification Suitable Areas: Low-VOC environmentally friendly coatings, decorative floor coatings, wear-resistant latex paints, abrasion-resistant topcoats, paper coatings Prohibited Scenarios: Lightweight weight-reduction filling systems, food-contact products, ultra-high-shear precision injection molding processes
