Get a Superior Finish on Solid Surfaces, Topcoats, Glass
3M™ Trizact™ Hookit™ film discs are suitable for use on a variety of solid surfaces, topcoats, and to accommodate most finish and process requirements. This disc is manufactured with the 3M™ Hookit™ attachment system for quick mounting and removal and to hold the disc securely in place during use. Hookit™ discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on rotary or random orbital tools, can be removed cleanly and easily, and can be re-used again and again for the life of the disc.

Better Results in Less Time, Fewer Steps
Unlike conventional abrasives, 3M™ Trizact™ discs start sharp and stay sharp, resulting in more predictable finishes and improved, consistent quality. 3M™ Trizact™ discs last longer than conventional discs and provided precise finish control such that operators can reduce grade sequences, requiring fewer process steps and fewer abrasive products. Three-dimensional structures uniformly distributed over the entire surface ensure consistent performance and eliminate disc-to-disc variation.

Cerium Oxide for Final Polishing
The 3M™ Trizact™ Hookit™ Film Disc 568XA uses cerium oxide abrasive mineral. Cerium oxide is an oxide of the rare earth metal, cerium. The average grain size of the particle is measured in nanometers in raw form, thus making it one of the most effective abrasives for final polishing steps on solid surfaces (PDF, 116 Kb). It is heat resistant and effective as a polishing agent for glass mirrors, plate glass, crystal, television tubes, ophthalmic lenses, precision optics, precious, and semiprecious stone.
