Clogging

 

In addition to using the correct coating and a heat-resistant bonding agent, the risk of clogging can be reduced by using products which have a special stearate top coat.

This layer effectively absorbs frictional heat created by dry sanding, and increases the lifetime of abrasive products which are on the finer end of the grit scale, especially when sanding surface treated materials (varnish, paintwork etc.)
