Discs with paper backing, self-fastening PS 33 CK 3-3/4 (inch) 80 grit

This abrasive paper is composed of a paper backing (C-paper), which is covered in aluminium oxide grain with a semi-open coating. The grain is bonded to the paper backing (C-paper) by means of synthetic resin. The C-paper gives the abrasive paper the stability needed while keeping the paper flexible enough to contour snugly to the surface to be sanded. The semi-open coating means that 70 to 80 % of the paper backing are covered with abrasive grain. This coating leaves behind an adequate number of spaces between the grains to prevent clogging with dust and debris. Meanwhile, it also allows for a higher stock removal rate.
