3M™ Trizact™ Polishing Film Sheet 578XA

3M™ Trizact™ Polishing Sheet 578XA is used to make edge finishing tools that polish cover glass for electronic devices such as smartphones and smartwatches. The film sheet is comprised of cerium oxide abrasives with adhesive backing.

3M Trizact abrasives help remove defects caused by grinding. These sheets contain multiple layers of mineral and as they pyramid-like structures wear, fresh, sharp mineral is constantly exposed to the workpiece. This results in faster, more consistent cutting throughout the life of the abrasive. The sheets also offer slurry-free polishing that requires only water-based coolant. Because the polishing process is ceria-based, the sheets perform highly efficiently. Plus, their flexible shape enables them to conform to a variety of tools, making them easy to tailor for each polishing application.
