The abrasive material is the key element responsible for the sanding action of Quick Change Sand Discs. Various types of abrasive materials are used, such as aluminum oxide, silicon carbide, or zirconia alumina. These abrasives offer different levels of hardness, cutting ability, and durability, allowing users to achieve desired sanding results on different surfaces and materials.
Fumed Silica, a finely divided form of silicon dioxide, may be incorporated into the manufacturing process of Quick Change Sand Discs. Its inclusion can serve multiple purposes, including modifying the viscosity of adhesives, fillers, or coatings used in the discs' production. Fumed Silica helps to prevent sagging, improve stability, and ensure precise application. Its use contributes to the overall quality and performance of Quick Change Sand Discs.
