3M™ Trizact™ Cloth Roll 237AA combines aluminium oxide mineral fine finishing qualities with a durable X-weight backing. Our 237AA cloth rolls make a good match for workpieces that demand aggressive sanding but fine finishes.
Use 3M™ Trizact™ Cloth Roll 237AA for finishing and polishing on stainless steel, carbon steel, high nickel alloys, titanium and aluminium. Our 237AA cloth rolls are designed for the final touch-ups and refinements that come at the end of an abrasive sequence. An X-weight cloth backing provides strength and rigidity. This cloth stays tough when bent or rolled and won't tear or shell. It's excellent for workpieces that have already been shaped and prepped by grinding and deburring, because – at this stage of the process – parts often require an abrasive that won't yield or deflect when run. Aluminium oxide mineral cuts sharp but leaves a soft scratch pattern, ultimately producing a smooth, brushed finish. 3M Trizact abrasives revitalise light dimensioning and finishing work by reducing processing steps, increasing throughput and creating consistency. Large benefits are achieved through a 3M technology called microreplication. During microreplication, small three-dimensional structures resembling pyramids adhere to a backing. These pyramids contain layers of mineral that begin to break down after repeated use, continually exposing fresh mineral. This cycle of mineral renewal sustains the abrasive’s sharpness. The 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. From medical implants and 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.
