However, unlike steel wool, the Scotch-Brite 7448 PRO disc won't rust after use or create fine metal splinters. It also cleans upholstery and chrome. This versatile product is effective in wet or dry environments and can be rinsed and used over and over again. We filled this gray disc with ultra fine silicon carbide abrasive mineral, a synthetic mineral that is very sharp and commonly used for low pressure applications such as paint prep. While it breaks down faster than aluminum oxide, it produces a smoother finish. Scotch-Brite PRO is a unique surface conditioning product with abrasives incorporated into non-woven nylon fibers. Breakthrough fiber coating technology allows Scotch-Brite PRO abrasive products to cut faster and produce a more consistent scratch than competitive non-woven abrasive products, reducing the time and effort it takes to finish parts. Combining abrasives with the fibers gives you an abrasive system that delivers consistent results for the life of the product. The open web material is load-resistant and keeps the abrasive minerals cutting at high performance by limiting clogging of the nylon fibers.
