3M-237AA Trizact Abrasive Belts

The 3M™ Trizact™ 237AA abrasive cloth utilizes 3M’s innovative micro-replication technology. In this process, fine-micron-grade aluminum oxide particles are formed into tiny pyramids and applied to a durable X-cloth backing. During the sanding process, these pyramids wear down evenly, continuously exposing fresh, sharp abrasive grains. This maintains consistently high cutting performance and produces a precise, predictable finish.

The self-sharpening pyramids cut cooler and more efficiently than conventional abrasives, thereby guaranteeing a significantly longer service life. Thanks to the flexible fabric backing, the sanding belt adapts perfectly to contoured surfaces and delivers a uniform result—ideal for intermediate sanding and fine polishing prior to coating or buffing.

The uniform grain distribution across the entire belt surface produces a particularly fine finish that requires fewer work steps and thus saves time. The synthetic resin-bonded abrasive mineral is heat-resistant and prevents grain loss, while the film backing ensures smooth belt run without chatter marks.

Compared to conventional abrasives, 3M™ Trizact™ cloth belts achieve up to five times longer service life and deliver a finer finish at higher processing speeds. This reduces process steps and noticeably increases productivity.
