3M™ Trizact™ Roloc™ Cloth Disc 237AA uses proprietary microreplication technology where micron-graded aluminum oxide particles are formed into tiny pyramids of abrasive mineral and then coated on an X weight cloth backing. As these pyramids wear, fresh, sharp mineral is continually exposed to produce a consistent cut and a predictable, fine finish. The abrasive and resin structure for the 3M™ Trizact™ Cloth Disc 237AA is formulated to break down under medium pressure and keep fresh, sharp mineral cutting to provide consistent finishes on hard metals such as carbon and stainless steel. Our disc also features a grinding aid that helps prevent heat buildup, warping and discoloration. The belt is constructed on an X-weight, durable cloth backing that helps provide control, conformability, and effective medium-pressure grinding. The resin bonded abrasive gives you greater heat resistance and helps prevent delamination. When compared to conventional abrasive products, proprietary Trizact™ abrasives produce a finer finish, achieve results faster, and last longer. Robotic metal polishing demands the most consistent, refined cut and long abrasive life. 3M™ Trizact™ abrasives can consistently deliver near-mirror finishes while also delivering the abrasive life that helps reduce changeouts and downtime in robotic cells. This helps maximize the efficiency of the cell, allowing you to produce more parts per disc.

• Self-sharpening pyramids start sharp, stay sharp, and run cooler than conventional abrasives
• Flexible backing for consistent finish over contours
• Three-dimensional design enables very consistent finishes throughout the abrasive life in robotic applications
• For intermediate finishing and fine polishing prior to plating or buffing
