What size of white fused alumina is used for floor wear-resistant layers?
For floor wear-resistant layers, the most common size of white fused alumina used is in the range of 150 to 320 grit . The specific size you choose will depend on the type of flooring and the application method.
Here is a breakdown of the recommended sizes for different flooring applications:
| Application Type | Recommended Size (Grit) | Corresponding Particle Size | Key Characteristics & Use Case |
|---|---|---|---|
| General Floor Coatings | 150# – 320# | ~40 – 90 μm | Commonly used for high-performance coatings in industrial plants and parking lots. Provides excellent wear and scratch resistance . |
| Epoxy Floor Coatings | 180# – 280# | ~50 – 70 μm | Added directly to water-based epoxy coatings to increase durability and slip resistance . |
| Wood Floor Coatings | 180# – 240# | ~53 – 75 μm | Used in wear-resistant layers for laminate flooring, often impregnated into paper or UV-cured coatings for high-traffic areas . |
| Ceramic Tile Anti-slip | 220# – 280# | ~45 – 65 μm | Coarser particles used as an anti-slip agent in tile manufacturing . |
| Ultra-fine Coatings | 1500# – 2000# | ~8 – 15 μm | Used in UV-curing wood coatings where transparency and a smooth finish are needed, while still improving scratch resistance . |
🔍 How to Choose the Right Size
Selecting the correct grit size involves balancing two main factors:
For higher wear resistance and anti-slip properties: Choose coarser grits like 150# to 220#. These larger particles create a tougher, more textured surface ideal for industrial floors or areas with heavy foot traffic.
For a smoother finish and better transparency: Choose finer grits like 240# to 320# or higher. These are better for applications like decorative concrete or wood floors where the appearance and feel of the surface are as important as its durability.
For most general-purpose industrial and commercial floor wear layers, 180# or 220# grit are the most frequently cited and versatile options .
