Product Description:
Mirka Polarstar SR 1.25" Channeled PSA Rosette Discs, 2,500 grit (7 micron) 100 Disc Package (SR-301-7A) is the first in a series of new high technology micro products produced by Mirka.
Polarshine SR 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 processes where the abrasive’s strong bonding ensures a long working lifespan.
Perfect for use with Mirka 1.25" (32mm) Quick Lock Backup Pads such as 1125S-R.
Sold 100 discs per package. Polarstar SR rosettes are available in other grits, click here for more information.
