3M 7747 Scotch-Brite™ Primer Prep Scuff Pads, 4 3/4″ x 15′ Roll

The most aggressive of the 3-part Scotch-Brite™ scuff pad system, the Primer Prep Scuff Pad is used to scuff prior to primer for proper mechanical adhesion. The aluminum oxide mineral offers an aggressive and clean cut. The unique non-woven web binds together synthetic fibers and abrasive particles to create a conformable, three-dimensional material with superior performance. Open structure reduces the risk of warping or discoloring the part, resists loading, improves finish and prolongs the pad’s life. 4 3/4″W x 15’L roll includes perforations every 4 3/4″ for easy pad tear off.
