Bonded vs coated abrasives
What it is
The two main abrasive formats. Bonded abrasives are grains held in a vitrified or resin matrix and formed into wheels for grinding and cutting; coated abrasives are grains bonded to a flexible paper or cloth backing, used as belts, discs and sheets for sanding and finishing
Bonded serves metal removal, coated serves surface finishing
Impact on industries
- Both are consumables tied to manufacturing activity, so demand recurs with industrial output rather than with capital cycles
- Serving both formats gives access to the full metalworking and woodworking customer base through one distribution network
- Standard grades are commoditised and exposed to low-cost imports, so margin depends on grade mix rather than volume
- Bonded is more technically demanding and capital-intensive; coated is faster-moving and more distribution-driven, so the two need different commercial models
