Black silicon carbide 120# 180# wear-resistant corundum for Epoxy coatings/epoxy floor paints
Product Name: Black Silicon Carbide (Black SiC)
Grit Sizes: 120# (coarse) and 180# (medium-fine)
Application: Anti-slip and wear-resistant filler for epoxy coatings, epoxy floor paints, and industrial flooring systems
Black Silicon Carbide 120# and 180# are high-performance, angular-shaped aggregates specifically engineered for use in epoxy floor coatings and paints. When incorporated into epoxy resin systems, these hard, dense particles significantly enhance the surface’s resistance to abrasion, impact, and slipping. They are the ideal choice for industrial flooring, parking decks, warehouses, and commercial kitchens where durability and safety are critical.

Why Choose Black SiC for Epoxy Floors?
A. Superior Wear Resistance
With a Mohs hardness of 9.5 (second only to diamond), Black Silicon Carbide is significantly harder than silica sand, quartz, or aluminum oxide. When broadcast onto wet epoxy coatings, it creates a rock-hard surface layer that withstands heavy forklift traffic, steel-wheeled carts, and constant foot traffic without powdering or eroding.
B. Excellent Anti-Slip Performance
The sharp, angular particles of 120# and 180# grits provide a uniform, textured finish that dramatically increases the coefficient of friction. This makes epoxy floors safe to walk on even when wet or oily – a critical requirement for food processing plants, auto repair shops, and loading docks.
C. Chemical & Thermal Stability
Black Silicon Carbide is inert to most chemicals (acids, alkalis, solvents) and retains its hardness up to 1,400°C. It will not react with epoxy resins, cause discoloration, or degrade under UV exposure or temperature fluctuations.
D. Aesthetic Appeal
The deep black color of the SiC particles creates a speckled, granite-like appearance when combined with colored epoxy paints. This hides dirt, scuff marks, and wear patterns, keeping floors looking cleaner for longer.
