Is there anything unique about the abrasive material made for these paper sheets?
; Yes! They feature aluminium oxide abrasive mineral which delivers high cut-rate yet offers consistent and uniform finishes.
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 issue of loading, which often occurs when sanding soft materials, is effectively addressed by this open-coat construction. By reducing the clogging of the abrasive, the usable life of the sandpaper sheet is extended.
