The 3M™ Hookit™ Green Corps™ paper abrasive disc 750U is built for tough sanding jobs in collision repair. Coarse grade ceramic and aluminum oxide blend abrasive is resin bonded to durable e weight paper backing for heat resistance, with open coat construction that reduces loading. Sheets are ideal for shaping plastic filler and putty, paint removal and scratch refinement on bare metal. Built to hold up during the most demanding auto body sanding jobs, 3M™ Hookit™ Green Corps™ paper abrasive disc 750U features a sharp, tough blended grain and durable e weight paper. It is resin bonded to resist heat during sanding of flat or difficult surfaces. And our Hookit™ attachment system makes disc change outs fast, easy and cost effective during multi-step sanding processes. Ceramic 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™ Green Corps™ 750U features a heat resistant resin bond which makes it suitable for a wide range of body repair applications. The Hookit™ attachment system has a hook and loop feature which makes disc attachment, removal, and re attachment clean and easy. It also facilitates use and reuse of the disc for maximum product life. Hookit™ discs have a brushed nylon loop backing of the type most commonly used in everyday hook and loop applications. 3M™ Hookit™ disc pads (sold separately) feature hooks which grip the brushed nylon loop backing. It's simple: just attach the disc and start sanding. The disc removes just as cleanly and easily. The Hookit™ system is designed for work spaces and applications where adhesive backed discs may become contaminated by dust, dirt, or flying debris. Our 3M™ Hookit™ Green Corps™ paper abrasive disc 750U is built for long life even for tough auto body sanding projects. From its ceramic and aluminum oxide mineral abrasive to its Hookit™ hook and loop attachment, this disc is another way that 3M™ applies science to make life easier for professionals in collision repair.
