ABSTRACT:
An abrasive or sanding disc for use on a rotary or double action backup pad is provided on its rear surface with a smooth flexible coating to give strength to the sandpaper and to stick to a feathering adhesive on a backup pad. The smooth coating is typically a nylon coating or an adhesive which bonds to the back of the sandpaper and acts as a coating; this coating also adheres strongly to a feathering adhesive on a backup pad. The sanding disc can be strongly secured to the backup pad but can be pulled away from it, leaving the feathering adhesive on the backup pad.
