Product Description

Product Description

Aluminum oxide is a highly durable mineral that maintains sharp points on the grains for a longer period compared to natural abrasives like emery or garnet. The sandpaper features an open-coat construction where the abrasive grains are attached with some space between them. This design helps minimize the accumulation of dust on the paper's surface, preventing the abrasive points from getting clogged. The clogging of abrasive points often occurs when sanding soft materials, which can significantly reduce the lifespan of the sandpaper sheet.
