Coated Abrasives Types Components and Uses

1. COATED ABRASIVES: TYPES, COMPONENTS, & USES

2. Coated abrasive is produced by bonding abrasive grains to backing material or flexible substrate using adhesives. Paper, fabric, vulcanized fiber, and plastic films are widely used as a backing material.

3. APPLICATIONS OF COATED ABRASIVE • The coated abrasives are produced in "jumbo" rolls and then cut into various shapes such as belts, discs, rolls, and sheets for surface treatment and polishing applications. • Sanding rolls and sanding belts, typically for non-precision operation, are commonly coated abrasives for physical applications. These two styles are known as symbolic coated abrasives by the general public.

4. STORAGE AND HANDLING OF COATED ABRASIVES Abrasives performance can be affected by improper storage of coated abrasives. Both types of backings are subject to temperature and humidity fluctuations during storage: • Keep the storage area at steady humidity (35-50 percent) and temperature (60-80 °F) levels. • Keep cartons away from damp or cold walls and floors where moisture can be absorbed. • Store coated abrasives away from any source of heat. • On shelves or pallets, shop bulk rolls flat, not on the side. • On shelves or pallets, shop bulk rolls flat, not on the side.
