The Difference Is in the ConstructionOne of the characteristics that makes 3M™ Trizact™ PSA Film Disc roll 268XA a standout among our other 268XA products is that it has a pressure-sensitive adhesive backing. Equipped with this attachment, attaching 268XA to backup pads and hand blocks becomes as easy as adhering a sticker. By applying a little pressure, operators have an abrasive that’s ready to use, enhancing overall productivity and throughput.3M™ Trizact™ PSA Film Disc roll 268XA also has a polyester backing, which makes it water resistant. As 268XA is commonly used for applications like wet sanding, it’s helpful to have an abrasive that can be run wet or dry. Moreover, using a lubricant like water can help wash away excess debris, preventing it from discoloring the substrate. While it may be run damp, one of the benefits of the disc is that it requires little water for effective results.3M Science, Applied with 3M Microreplication Technology3M™ Trizact™ PSA Film Disc roll 268XA uses proprietary 3M microreplication technology, encapsulating aluminum oxide mineral inside tiny pyramids. These pyramids are evenly distributed over a polyester backing. While conventionally coated abrasives have erratically spaced mineral, Trizact™ abrasives focus on uniformity. As pyramids wear, fresh, sharp mineral is exposed to produce a consistent cut and a predictable, fine finish.Great Versatility3M™ Trizact™ PSA Film Disc roll 268XA is available in a range of grades so operators can choose the right grade for their unique application; the lower the A-grade, the finer the grade. So, operators should select a smaller grade, like A5, for a fine finish and a larger grade, like A35, for a coarser finish. Discs are color-coded by grade, to reduce the risk of mistakenly selecting the wrong grade in a sequence.Regardless of the grade selected, operators can rely on great performance with 3M™ Trizact™ products. Operators turn to 3M™ Trizact™ PSA Film Disc roll 268XA to bring workpieces one step closer to a matte, semi-gloss or high gloss finish.About the PSA AttachmentThis 3M™ Trizact™ PSA Film Disc roll 268XA has a pressure-sensitive adhesive (PSA) to make for easy abrasive to tool attachment and increased efficiency. The PSA backing works much like a sticker, whereby operators can stick the disc to the tool by applying light pressure.
