Product Description: Aluminum Oxide Sandpaper

Aluminum oxide is an exceptionally durable mineral that retains its sharpness for extended periods compared to natural abrasives like emery or garnet. The abrasive grains are securely attached to the sandpaper using an open-coat construction technique, which creates space between the grains. This design helps prevent the accumulation of dust on the paper's surface, which could otherwise hinder the abrasive points. The issue of loading, commonly encountered when sanding softer materials, is effectively minimized. By reducing clogging, the open-coat construction extends the lifespan of the sandpaper sheet, ensuring optimal performance.
