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.

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.
