Tough Discs for the Toughest CoatingsWe developed the 3M™ Hookit™ Hard E-Coat Abrasive Disc for consistent finishes, better paint adhesion and reduced costs when sanding the latest, hardest OEM primers and e-coats. These durable discs are engineered for some of the toughest jobs in collision repair: scuff sanding electro-coated primers on new OEM panels, or featheredging hard ceramic OEM clear coats. Long-lasting, fast-cutting diamond grade mineral blend leaves a consistent matte finish at the equivalent of P320 for consistent and effective paint and topcoat adhesion.Diamond Grade Mineral Blend for Hard E-CoatsThese discs feature a specially-designed diamond grade mineral blend developed for performance on some of the hardest surfaces in collision repair. Technicians can reliably create consistent matte scuff patterns on e-coats or featheredging on hard ceramic OEM clears, without resorting to extremely coarse grades that can cause uneven results or burn-through. And, since the diamond blend is significantly harder than the automotive surface, the disc lasts longer for increased productivity.Better Dust ManagementHookit™ Hard E-Coat Abrasive Discs are designed with small, precise spiral-patterned holes to give dust a better escape route, moving more dust away from your finishing surface without loading the disc. This helps the disc last longer, increases productivity and reduces material consumption.Our Hookit™ Attachment SystemThe 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 re-use 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 debris.Better Science for the Toughest Sanding from 3MThrough decades of developing our abrasives for collision repair, 3M has combined science, strength and smoothness - from diamond grade mineral blend to fast, easy attachment to spiral hole patterns for dust management. The 3M™ Hookit™ Hard E-Coat Abrasive Disc is an example of how we apply science to the latest, toughest sanding jobs, meeting the specific needs of collision repair technicians in a fast-developing field.
