Effectively Remove Burrs and Contaminants without Damaging Base Material
Scotch-Brite products can help make your tough jobs easier. The Scotch-Brite AL Surface Conditioning Disc, specifically, helps achieve burr-free, paintable finishes in fewer steps without damaging the base material. It’s designed to lightly grind, finish and blend ? using its unique blend of open web and mineral to minimize imperfections and deliver a fine finish. It excels on soft substrates and applications where loading is the cause of the end of the abrasive life.

Aluminum Oxide Mineral Cuts Fast and Sharp
Aluminum oxide mineral is interspersed in the disc’s open web. Aluminum oxide is a popular choice among industrial professionals given its durability and sharp cut. Moreover, aluminum oxide is known for being friable, meaning it fragments under heat and pressure in order to self renew. Friability keeps the mineral cutting sharp. While all discs use aluminum oxide, we offer Scotch-Brite AL Surface Conditioning Disc in three grades: very fine (VFN), medium (MED) and coarse (CRS). In this way, operators can choose a grade that’s tailored to their substrate and desired finish.

Hook and Loop for Easy Power Tool Attachment
We included a a Hook and Loop attachment on this disc so operators could easily swap between discs when there are multiple grades in a sequence enhancing overall productivity. Abrasive material is pulled through the scrim on the back of the disc to create loops. Subsequently, loops mate to hooks on Hook and Loop backup pads (sold separately) which connect to tools. Altogether, the Hook and Loop attachment system makes disc to tool attachment swift and easy.

The Scotch-Brite Advantage
Scotch-Brite products incorporate mineral into non-woven nylon fibers. Breakthrough fiber coating technology allows Scotch-Brite abrasive products to cut faster and produce a more consistent scratch.

The open-web material is load resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the nylon fibers. As the nylon fibers break down gradually during grinding, they expose fresh mineral, so you get a consistent sharp cut ? part after part.
