Minimal clogging thanks to the semi-open coating on a paper backing (B-paper)

Klingspor furnishes their abrasive sheets PS 73 BW with a paper backing (B-paper). Paper backings are grouped into classes A though G based on their mass per unit area. A-papers are the lightest, while G-papers are the heaviest. Consequently, the backing used for the abrasive sheets PS 73 BW is rather light. The abrasive grain coating covers between 70 % and 80 % of the surface. Referred to as semi-open, this type of coating leaves a number of spaces between the abrasive grains, allowing for an effective discharge of abrasive dust, chips and other debris. Despite its high removal rate, the PS 73 BW has a minimal tendency to clog during sanding on varnish, filler, paint and plastic. This allows for expedient work without any interruptions.

Extraordinary service life thanks to added active agent coating

This abrasive by Klingspor comes with a top coating made of synthetic resin that complements the base coat. This coat firmly secures the abrasive grain in the base coat and supports the grain against lateral forces at the same time. Solid and distinguished by strong adhesive force, synthetic resin always delivers the same consistent qualities thanks to its synthetic manufacturing process. It also provides for a long service life. The service life of the abrasive sheets PS 73 BW is further enhanced by an added coat with active agents. The PS 73 BW abrasive by Klingspor performs exceedingly well and for a long period when used for smoothing filled surfaces, the processing of plastics and the sanding of varnished and painted surfaces.
