Designed to be Flexible3M™ Hookit™ Microfinishing Film Sheet 468L is manufactured with an open-coat surface to increase efficiency and product life by minimizing loading. The abrasive is resin-bonded and supports flexibility without sacrificing durability and reliable performance under high heat and pressure. To complement the effective abrasive action, the polyester film backing flexes to help achieve a consistent finish over contours and offers greater tear resistance than comparable paper products, making it ideal for high-production environments.Silicon Carbide AbrasiveThe 3M™ Hookit™ Microfinishing Film Sheet 468L features precision, micron-graded silicon carbide – a popular choice among industrial professionals because of its fast cut-rate and smooth finish. Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications like paint prep.3M™ Hookit™ Attachment3M offers a complete line of hook-and-loop style 3M™ Hookit™ abrasives for work spaces where adhesive-backed abrasives may become contaminated by dust or dirt. Hookit™ products conveniently attach to a hook-and-loop backup disc pad (sold separately), can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life. The backup pad typically attaches to a tool like a random orbital sander (also sold separately).
