3M™ Trizact™ Stikit™ cloth disc 337DC provides fast scratch removal on automotive metal components and leaves a superior finish. Premium aluminum oxide macro replicated grain on an X-weight backing combine to contribute to long product life. Our 3M™ Trizact™ Stikit™ cloth disc 337DC works well for automotive white metal repair. It is ideal for blending and finishing minor defects and for use to remove scratch marks left behind by metal files or rotary tools. It provides a very fast scratch removal capability combined with a superior finish, leaving the surface ready for e-coat application. This cloth disc is available in grades of A300 and 5 in Dia, as well as make to order sizes. Macro replication is the technology behind the geometrical bricks-and-channels abrasive structure of our 337DC products. These unique abrasive bricks contain up to four times as much mineral as conventional abrasives. As the mineral breaks down, fresh mineral is exposed. The macro replicated pattern of Trizact™ 337DC discs generates minimal heat. The open spaces between the abrasive bricks channels heat away and removes swarf. This means you can use these discs on substrates like galvanized panels and aluminum hoods. Our 3M™ Stikit™ system abrasive products come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them is as simple as pressing on a sticker. And because the adhesive is pressure sensitive, the sheet can be peeled off of the pad just as easily, leaving a clean surface for your next sheet.
