3M™ Finesse-it™ Hookit™ Film Disc 460LA, A3 3MIL, Config

Essential Ingredients
Operators may wonder what makes 3M™ Trizact™ Hookit™ Film Disc 460L equipped to level defects efficiently. It's a combination of essential ingredients, including mineral, backing, attachment system and 3M™ Science.

3M choses silicon carbide, a very sharp synthetic mineral, for this abrasive. Silicon carbide is commonly used for low-pressure applications such as paint prep. While it breaks down faster than aluminum oxide, it produces a fine finish that's desirable when prepping surfaces for topcoats, without too much aggressive scratching. The backing is a flexible, waterproof 3-mil film backing that provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing.

3M™ Hookit™ Attachment
Hookit sanding discs 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. Hook and Loop Disc Pads have small plastic hooks that attach to loops on the back of the abrasive. Small tufts of fiber are pulled through scrim on the abrasive to create loops which, subsequently, attach to the hooks. The hook-and-loop feature makes disc attachment, removal and re-attachment easy and facilitates use and re-use of the disc for the extent of the abrasive life.

The attachment of Hook and Loop Disc Pads acts like a cushion, providing some shock-absorption and buoyancy, especially when compared to other attachment styles and holder pads. Hook and Loop Disc Pads are great for work spaces where adhesive-backed discs may become contaminated by dust or dirt and are often used in applications where an adhesive-backed disc may be too aggressive.

3M™ Science, 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 patented 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.
