Product Description
Norton Multisand abrasive sheets have an open coat for longer usage time by resisting loading and durable P-graded aluminum oxide for a more consistent finish. These sheets are used for hand or machine sanding a wide variety of materials, such as metals, wood, plastics, and fiberglass.
In coated abrasives, individual abrasive grains are spaced at a predetermined distance from one another. This is an open-coat sheet. An open coat covers 50 to 70 percent of the surface with abrasive grains, for greater flexibility and clog resistance than a closed coat, which covers 100 percent of the surface. An open coat allows for longer usage time because it clogs less, while a closed coat offers a finer surface finish than an equivalent open-coat abrasive. The paper backing is flexible, and offers a more consistent finish than a cloth or fiber backing, while being thicker and more durable than a polyester film backing.
