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
Ideal for intermediate finishing and fine polishing prior to plating or buffing
Produces finer finishes than conventional electrostatically coated abrasives
3M™ Trizact™ Cloth Belt 237AA uses proprietary microreplication technology by 3M 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.
