Abrasives

All these factors need to be considered to produce suitable coatings. The size and properties, as well as the orientation of the “grit” particles as they are deposited on the adhesive-coated backing, and the properties of the adhesive and backing materials themselves – all these factors need to be considered to produce coatings that are fit.

Grains of aluminium oxide and silicon carbide are commonly used as the material and resin adhesive is typically used to bond the grains to the backing paper. The range of materials, situations, and conditions in the workplace where sanding is required is matched by the large range of coated abrasives available to do the work, each with a unique combination of materials: the size of the grains; open or closed coat – how densely the grains are packed; whether there is a stearate coating to lubricate and prevent clogging; the flexibility (or rigidity) of the backing material; and its suitability for dry or wet sanding.

Abrasives come in all shapes and sizes, for example, discs, strips, triangles, sandpaper sheets, abrasive pads, abrasive sheets and abrasive rolls.

They are usually categorized into different groups depending on the type of material in the backing, for example, net backing. Mirka is the pioneer of the dust-free sanding revolution, led by the ground-breaking innovation Abranet® and net range. Traditional sandpaper is also a popular paper abrasive type. Paper abrasives have been always been popular, especially since it is now possible to make them with multihole configurations, allowing you to sand dustless.

Here you can find the most popular abrasives that Mirka offers, including net, sanding paper, film, non-woven, and foam abrasives.
