Norton has chosen to take this out of the Norton brand, and is now labeling it under the Merit brand. It is still the same great paper, just in a different package!
- Load resistant stearate coating
- Fiber reinforced backing
- High quality aluminum oxide
- Open-coat construction - More flexibility and clog resistance
- Water-based stearate coating - Extends abrasive life
- Paper backing is flexible, prividing a more consistant backing while being thicker and more durable than a polyester film backing
Merit 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.
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.
