Key Features

  • Load resistant stearate coating, fiber reinforced backing, and high quality zirconia alumina combine to give 3X the performance of typical aluminum oxide paper sheets
  • Zirconia alumina is self-sharpening and durable, allowing for a faster cut rate than aluminum oxide
  • Open-coat construction offers more flexibility and clog resistance than a closed-coat sheet
  • Water-based stearate coating resists loading for extended abrasive life
  • 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

Product Description

The Norton 3X abrasive sheet offers more durability over an uncoated abrasive while resisting chip loading. This sheet is used for paint stripping, sanding and finishing on composites and fiberglass, and all-purpose bare wood sanding.

Coated abrasives have individual abrasive grains spaced at a predetermined distance from one another. An open coat covers about 50 to 70 percent of the coated surface with abrasive, for greater flexibility and resistance to clogging than a closed coat, which has 100 percent grain coverage. An open coat allows for longer usage time by clogging less, while a closed coat offers a finer surface finish than an equivalent open-coat abrasive. This sheet is open-coat. The stearate coating offers more durability over an uncoated abrasive while resisting chip loading. Stearated abrasives are non-pigmented to eliminate color transfer to the work surface. These sheets are typically used on portable sheet sanders and portable file sheet machines.

Zirconia alumina is a self-sharpening abrasive that allows for a faster cut rate and longer life than aluminum oxide, due to its ability to fracture and refracture, creating new cutting edges. Zirconia alumina is often used for high stock removal on wood and metals.

Abrasives are used for a variety of applications from shaping a part to fine finishing, depending on the grit size. Low grit numbers like 40 are coarse and are used for removing excess material and shaping a part. High grit numbers like 400 are fine and help to create a smooth surface finish.

Norton Abrasives manufactures a wide variety of sanding, grinding, and polishing abrasives, and has been located in the United States since 1885. In 1990, Saint-Gobain purchased Norton, keeping its manufacturing facilities and offices in the same location. Norton/Saint-Gobain has been recognized as a Global 100 Sustainable Company, as well as earning ISO 9000 and 14001 certification for quality and environmental management standards.
