Quizplus · Accepted Answer

The description matches that of coated abrasives, which consist of abrasive grains bonded to a backing material such as paper or cloth. Bonded abrasives, on the other hand, are made by permanently bonding abrasive grains together into a solid shape, while bond coats and abrasive coats are not commonly used terms in the context of abrasives.
