Preparation and Restoration
3M™ Trizact™ Hookit™ Film Disc Roll 466LA is available in three grades: A3, A5, and A7. The abrasive is color-coded by grade to help reduce the likelihood of reaching for the wrong grade during a sequence.

The discs in our 3M™ Trizact™ Hookit™ Film Disc Roll 466LA are made with silicon carbide mineral. We chose silicon carbide, a very sharp synthetic mineral, because it is commonly used for low-pressure applications such as paint repair. While it breaks down faster than aluminum oxide, it produces a fine finish that's desirable when prepping or restoring surfaces.

Hookit™ Attachment
3M™ Trizact™ Hookit™ Film Discs have hook and loop attachments on the back of the disc. Small tufts of fiber are pulled through scrim on the abrasive to create loops which, subsequently, attach to the hooks on Hook and Loop disc pads. These features makes disc attachment, removal and re-attachment swift and efficient. Moreover, they facilitate use and re-use of the disc for the extent of the abrasive life.

3M™ Science and the Power of Trizact™ Abrasives
3M™ Trizact™ abrasives revitalize light dimensioning and finishing work by reducing processing steps, increasing throughput and creating consistency. Big benefits are achieved through a 3M technology called microreplication. During microreplication, small three-dimensional structures resembling pyramids are adhered to a backing. These "pyramids" contain layers of mineral, and they begin to break down after repeated use, continually exposing fresh mineral.

The cycle of mineral renewal sustains the abrasive's sharpness. Ongoing sharp cutting action reduces the need to swap out the abrasive, contributing to higher throughput and increased productivity. Additionally, because mineral is uniformly distributed over the abrasive surface, the workpiece receives fixed — rather than erratic — contact for a consistent cut. From medical implants to surgical tools to automotive transmission components, 3M™ Trizact™ abrasives are uniquely suited for projects with acute technical requirements — delivering a consistent finish part after part.
