COATED ABRASIVES 101

Coated abrasives are manufactured in “jumbo” rolls then cut into different shapes like: - Belts - Discs - Rolls - Sheets - Flap Discs - Flap Wheels & Specialties.

 Abrasive grains such as aluminum oxide, silicon carbide, zirconia alumina, garnet & emery are bonded to a flexible substrate using adhesives.

Commonly used substrates include paper, cloth, fiber, & polyester films.

Grit sizes range from very coarse to ultra-fine.

Coated abrasives are used for surface-treatment & polishing applications in manufacturing sectors such as furniture & cabinet making, marine, automotive, welding, foundry, aerospace, & do-it-yourself markets.
