An Introduction to Abrasives Products

Abrasives products are classified into bonded abrasives and coated abrasives.

1. Bonded Abrasives

Bonded abrasives are natural or synthetic abrasive grains "bonded" into a solid form, usually in the shape of a wheel. Bonded abrasives products also include grinding and cut-off wheels, snagging wheels, segments, mounted wheels, plugs, and cones. Grinding wheels are cylinders that are rotated at high speed. Due to different abrasives, bonding agents, and manufacturing techniques, grinding wheels differ greatly in performance, which rests with abrasives, grits, bonding agents, organization, shapes, sizes, etc.

Classified by shape:

Grinding wheels: straight grinding wheel, straight cup grinding wheel, tapered wheel, cylinder wheel, dish wheel.

2. Coated Abrasives

A coated abrasive comprises an abrasive fixed to a backing material such as paper, cloth, rubber, resin, polyester or even metal, many of which are flexible.

Classified by shape:

Classified by application:

Sanding sponge: A Sanding sponge is a special kind of sponge used for the replacement of blocks and traditional sanding screens used in drywalls. Typically, a sanding sponge is utilized in a slightly damp condition and needs to be rinsed and wrung during the wet sanding process.

Dry sanding paper: rough processing and polishing, such as iron pipes and metal.

Waterproof sanding paper: Waterproof paper sanding paper are the ultimate performer for wet applications. Typical applications include light-duty metal sanding, primer sanding, defect removal from painted surfaces, filler sanding, sanding and finishing of composites and fiberglass, bare wood sanding, and sanding between sealer coats. Paper sheets are typically used hand or jitterbug sanding.
