Professional-Grade Ceramic and Aluminum Oxide MineralsCeramic and aluminum oxide minerals are popular among industry professionals because of their durability and dependability. These minerals make a tough, durable abrasive that provides fast cut rate, hardness, strength and low heat retention. 3M™ Stikit™ Green Corps™File Sheet 246U features a heat-resistant resin bond which makes it suitable for a wide range of body repair applications.Resists Dust and DebrisOpen coat construction means the abrasive grains are placed with space between them to help evacuate sanding dust and other debris to avoid clogging the cutting edge of the grains. The load-resistant coating on the abrasive grains also allows the sheet to continue cutting even when sanding paints and other materials that would otherwise clog the sheet and hinder sanding ability. All of this adds up to increased productivity and reduced material consumption.The Speed of Stikit™ Attachment3M™ Stikit™ Green Corps™File Sheet 246U come ready-to-use with Stikit™ attachment that features a pressure sensitive adhesive coating on the backing - simply press the sheet onto a sanding block and you're ready to go. They remove just as cleanly, leaving an uncontaminated surface for the next sheet.Better Science for Better Sanding from 3MFrom its abrasive to its fast, easy Stikit™ attachment, our 3M™ Stikit™ Green Corps™File Sheet 246U is another example of how 3M applies science to life - making collision repair operations better and more efficient.
