Finish and Repair Sensitive Surfaces3M™ Trizact™ PSA Film Roll 568XA is used to create abrasive discs and belts with defect repair in mind. Sensitive surfaces like glass, acrylic and corian require an abrasive that cuts aggressively without significantly gouging or scratching the surface. This roll features microreplicated pyramids of natural cerium oxide grains, which cut consistently and produces a high gloss level desirable during surface finishing. The 2.0 mil. film backing is water resistant for touch-ups and debris removal.Swift Tool AttachmentThe pressure-sensitive adhesive (PSA) on the back of 3M™ Trizact™ PSA Film Roll 568XA abrasives make power tool attachment as simple as pressing on a sticker. The PSA backing adheres firmly to a backup pad when light pressure is applied, and can be peeled off just as easily, leaving a clean surface for the next abrasive in the sequence. With only a thin layer of adhesive standing between the abrasive and the backup pad, power is transmitted directly to the workpiece surface and there are fewer barriers that limit the abrasive's ability to sand aggressively. Convenient liners reduce contamination of the adhesive before use, maximizing adherence.The Trizact™ Advantage3M™ Trizact™ abrasives revitalize light dimensioning and finishing work by reducing processing steps, increasing throughput and creating consistency. Big benefits are achieved through a proprietary 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 the mineral is uniformly distributed over the abrasive surface, the workpiece receives fixed – rather than erratic– contact for a consistent cut.
