Coated Characteristics

Although considered a ‘single-layered’ structure due to its one-directional op-
eration, coated abrasives consist of resin bonding agents and abrasive grains
layered and adhered to a supportive backing . The structure of coated abrasive
materials offers more aggressive cutting action, simply considering the lack of
compression and conformability to surfaces .

The dense organization of abrasive grains provides more friction, which results
in cutting power, but also creates more heat . To combat excessive heat, proper
grain selection is made based on metal type . Harder metals require a sharper
grain to penetrate and cut, versus softer metals that are easily worn away . The
addition of a grinding aid or stearate acts as a friction reducer, resulting in more
efficient cutting action .
