Product Description
The Norton H875 NorZon Plus zirconia alumina abrasive and open-coat design offer reduced loading and high durability, for longer disc life. The pressure-sensitive adhesive forms a bond when pressure is applied to stick the disc to its back-up pad, without the use of solvents, water, or heat to activate the adhesion. This disc is suitable for sanding fiberglass and composites.
Coated abrasives have individual abrasive grains spaced at a predetermined distance from one another. This is an open-coat disc. 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 strong E-weight paper is durable yet flexible (paper is measured on a scale from A to F, where F is heaviest). 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. Pressure sensitive adhesive sticks when pressure is applied, without messing with solvents, water, or heat. This disc is suitable for use with a die grinder or orbital sander. Use with molded-rubber back up pads on a grinder. Use a hard pad for aggressive cutting, a medium pad for general-purpose applications, or a soft pad for contours and fine finishing work. Or, with a random orbital sander, use a foam back up pad to match the application. Foam pads can come in different combinations of shape and density for finer or more aggressive work. For example, use a low profile for uniform contact with the work surface or a tapered edge for small contours or inside corners, soft density for 320 grit and finer sanding, and medium density for grits coarser than 320.
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.
