3M™ Trizact™ Cloth Belt 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.

• Self-sharpening pyramids start sharp, stay sharp, and run cooler than conventional abrasives
• Flexible backing for consistent finish over contours
• Ideal for intermediate finishing and fine polishing prior to plating or buffing
• Produces finer finishes than conventional electrostatically coated abrasives
• Produces finer finishes than conventional electrostatically coated abrasives
