A coated abrasive product is made up of three basic raw materials: an abrasive mineral, the backing onto which the abrasive is applied, and an adhesive bond. The Carborundum Abrasives coated abrasive marking system includes both a generic and a technical marking.

The generic markings identify the abrasive type, backing, bond, and any special features and/or tradenames. An example would be: Premier Red Aluminum Oxide Dri-Lube Resin Paper Open.

The technical markings identify the actual components which make up the product. Technical markings consist of up to 10 parts. An example would be: P400 B 0912 DO. The following terminology explains the technical marking system.
