Polarstar SR is the first in a series of new high technology micro products produced by Mirka. It is a high precision sanding material developed mainly for use on spot repairs, such as at car plants in the finessing and hospital area of the paint shop.

Using Mirka’s innovative ‘Defined Mono Layer’ production technology has resulted in an even surface finish that enables quick polishing with excellent results. This manufacturing process is also energy efficient and has a low carbon footprint. The discs can be used for both machine and hand sanding operations and are primarily designed for wet sanding mode where the abrasive’s strong bonding ensures a long working lifespan.

Polarstar SR is the perfect finessing material for the correction of small painting defects and the removal of dust particles in topcoats and clearcoats. The discs are used in wet applications, by machine or by hand.
