White corundum 320 mesh for floor finishing varnish
Applying white corundum 320 mesh (particle size of about 40-50 microns) to floor finishing varnish can significantly improve the overall performance of the coating, especially suitable for high-demand industrial floors, commercial spaces or high-end home environments. The following are its core advantages:
1. Extreme wear resistance and scratch resistance
High hardness protection: White corundum (α-Al₂O₃) has a hardness of Mohs 9 and is evenly dispersed in the varnish to form a “micron-level armor” to resist mechanical wear such as forklifts, high heels, and heavy objects dragging, extending the life of the floor by 3-5 times.
2. High transparency and gloss retention
Fine particle size matching: 320 mesh particles are close to the lower limit of visible light wavelength (about 0.4 microns), with very little scattered light. Combined with high refractive index resins (such as polyurethane acrylates), the varnish can maintain a transmittance of >90%, highlighting the underlying color or pattern.
Anti-UV yellowing: White corundum itself is chemically inert, UV-resistant, and does not turn yellow after long-term use. It is suitable for exhibition halls and art galleries with good lighting.
3. Anti-slip and safety improvement
Controllable roughness: 320 mesh particles form a uniform micro-convex structure on the coating surface, and the dry static friction coefficient can reach 0.6-0.8 (about 0.4 for ordinary varnish), and the wet anti-slip property is improved by more than 30%, which meets the OSHA anti-slip standards (such as ANSI B101.3).
4. Chemical corrosion resistance and easy cleaning
Inert barrier: White corundum is highly stable to acids and alkalis (pH 2-12), oil stains, and solvents (such as alcohol and acetone). After silane coating, it can prevent corrosive media from penetrating the substrate.
Typical application：
Industrial floor: high-frequency mechanical wear areas such as warehouses and workshops.
Commercial space: places with high traffic anti-slip needs such as shopping malls, airports, and hospital corridors.
High-end home: basements, garages, open kitchens, etc., which are both beautiful and durable.
