3M Cubitron II Stikit Paper Sheet 732U features 3M Precision Shaped Ceramic Grain, a revolutionary advancement in abrasive technology. The triangular shaped ceramic mineral is designed to slice through the substrate, rather than gouging or “plowing” like conventional abrasives, resulting in a sheet that cuts fast and offers long life.Now available from grades 80+ through 1000+, these sheets are designed for a wide array of substrates and applications,providing flexibility and versatility in use. The sheets are effective for a broad range of tasks from stock removal to fine finishing on various substrates, including metals, paint coatings, composites, gelcoat, and different types of wood. The C-weight paper backing offers flexibility and is suitable for sanding applications where edge retention is not the main concern. The 3M Stikit system eliminates the time-consuming task of applying adhesive to the sheet backing. These high-quality, coated abrasive products come ready to use with a pressure sensitive adhesive coating on the backside so that attaching them to your sheet pad 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 disc.
