An aluminum oxide disc constructed on an E-weight heavy paper backing. Resin-bonded for heat-resistance. Features an anti-loading stearate coating. 3M Stikit green Corps abrasive disc 255U excels at feather edging, filler shaping, paint removal and rough feather edging on automotive bodies. Green Corps products are made with a blend of abrasives including 3M high performance ceramic abrasive grain which provides increased abrasive life and a faster cut rate. Use these discs on the following surfaces - clear coats, fiberglass, filler, metal, paint and plastic. Open coat construction reduces loading on fresh filler. Our 3M Stikit green Corps abrasive discs are available in no-hole and dust-free configurations. Use these discs for dry sanding applications. These abrasive discs are made with our 3M Stikit system, which offers convenient disc changes between grades or applications. Stikit discs come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them to the disc pad is as simple as pressing on a sticker, yet they remove cleanly without leaving any sticky residue behind.
