3M Ceramic Microspheres W-410 Solid Ceramic Microspheres for Scrub- & Scratch-Resistant Coatings

Full Name & Product Positioning Product Full Name: 3M W-410 High-Whiteness Solid Ceramic Microspheres A white solid ceramic microsphere grade made of alkali aluminosilicate ceramic, with whiteness L value ≥90 and fine, uniform particle size. Commonly used for scrub resistance, abrasion resistance, scratch resistance, and hardening modification of coatings. Suitable for low-VOC environmentally friendly formulations. Used as a wear-resistant modifying filler for architectural coatings and industrial maintenance paints, improving coating durability and surface texture. Core Technical Parameters ·   True Density: 2.4 g/cm³ ·   Mohs Hardness: Grade 6 ·   Compressive Strength: >60,000 psi ·   Particle Size D50: 4 μm, D90: 21 μm ·   Whiteness (L value): ≥90 ·   Softening Point: 1020°C ·   pH Value: 9.0-12.0 (5% aqueous solution) ·   Physical Form: High-whiteness ultra-fine solid white powder ·   Material: High-purity alkali aluminosilicate ceramic ·   Core Characteristics: High whiteness, wear resistance, scrub resistance, abrasion resistance, high temperature resistance, low resin adsorption, suitable for low-VOC formulations Key Advantages ·   Good hardness and compressive performance, can improve coating scrub resistance and abrasion resistance, addressing wall coating wear, powder shedding, and gloss loss. ·   High powder whiteness and fine particles result in uniform coating color after filling, with minimal impact on the decorative effect of the coating base color. ·   Low resin adsorption allows formulation optimization, suitable for low-VOC environmentally friendly coating production. ·   Heat resistance, corrosion resistance, aging resistance, and UV resistance; 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: Interior and exterior architectural scrub-resistant coatings, industrial maintenance paints, light-colored industrial anti-corrosion coatings Suitable Areas: Low-VOC environmentally friendly coatings, decorative floor coatings, wear-resistant latex paints, abrasion-resistant topcoat systems Prohibited Scenarios: Lightweight weight-reduction filling systems, food-contact products, ultra-high-shear precision injection molding processes
