System description<br />
Mar resistance characterises the ability of a coating to resist damage<br />
caused by light abrasion<br />
The difference between mar and scratch resistance is that mar is related<br />
only to the very fine surface scratches which spoil the appearance of the<br />
coating<br />
Mar resistance depends on a complex interplay between viscoelastic or<br />
thermal recovery, yield or plastic flow, and fracture.<br />
The mechanical properties of polymeric clearcoats are rate and temperature<br />
dependent and viscoelastic recovery can cause scratches to change with<br />
time<br />
