White Fused Alumina 220# 240# for Water-Based Epoxy Floor Coatings
Product Overview
White Fused Alumina 220# is a high-purity, synthetic abrasive material specifically engineered for use in water-based epoxy floor coatings. With its excellent hardness (Mohs 9.0), uniform particle size, and chemical stability, it serves as an ideal anti-slip additive that enhances traction while maintaining a smooth, durable finish. This product is perfect for industrial, commercial, and decorative flooring applications where safety, durability, and aesthetics are critical.
Key Features
✔ Superior Anti-Slip Performance – Provides a micro-textured surface that significantly improves slip resistance, making floors safer in wet or oily conditions.
✔ High Purity & Chemical Stability – Free from iron and other impurities, ensuring no discoloration or reactivity with water-based epoxy systems.
✔ Excellent Wear Resistance – Harder than most floor additives, ensuring long-lasting performance even in high-traffic areas.
✔ Uniform 220 Grit Size (F220#) – Offers a balanced texture—aggressive enough for slip resistance yet fine enough for a smooth, walkable surface.
✔ Low Dust & Eco-Friendly – Compatible with water-based coatings, reducing VOC emissions and promoting a safer work environment.
✔ Bright White Color – Maintains a clean, professional appearance, ideal for light-colored floors where aesthetics matter.

Advantages Over Conventional Anti-Slip Additives
🔹 Longer-Lasting Than Silica Sand – Does not break down or wear away quickly under heavy foot or vehicle traffic.
🔹 More Consistent Than Polymer Beads – Provides uniform traction without clumping or uneven dispersion.
🔹 Safer Than Black Aluminum Oxide – No dark speckles, making it ideal for light-colored and decorative floors.
🔹 Better for Water-Based Systems – Unlike some aggregates, it does not affect the curing or adhesion of water-based epoxies.
