Electrocorundum F80 for sports court paint
Electrocorundum F80 (white fused alumina F80) is high‑purity electro‑fused aluminium oxide abrasive grain, widely used as anti‑slip and wear‑resistant functional filler for acrylic, polyurethane and epoxy sports‑court topcoat paint. WFA F80 grain size delivers balanced particle fineness, giving sports surfaces stable friction without sacrificing coating smoothness for basketball, tennis, pickleball and multi‑purpose outdoor courts.

Product Feature of Electrocorundum F80 for sports court paint
- High hardness: Mohs hardness 9.0. Sharp grain edges keep long‑term anti‑slip performance and resist polishing under frequent athlete shoe friction, outperforming common quartz‑sand fillers.
- Chemical inertness: Neutral high‑purity Al₂O₃ grain does not react with resin binders. It resists UV ageing, rainwater, acid‑base contaminants and avoids yellowing or discoloration of coloured court coatings for outdoor use.
- Good resin compatibility: Clean‑screened F80 grains mix smoothly into paint systems. It works well in roller‑applied, trowel‑coated or spray‑applied court coatings with low risk of nozzle clogging.
- Durable surface protection: Hard particles reinforce coating scratch‑resistance, reduce surface wear‑out, and extend the service cycle of sports‑court paint layers to cut maintenance costs.

Applications of Electrocorundum F80 for sports court paint
Blend F80 electrocorundum directly into the top finishing coat of sports‑court paint. Recommended adding ratio ranges from 3 %‑6 % by weight for most acrylic / PU court systems. It builds controlled surface roughness to reach standard anti‑slip index for sports venues.
