The 3M™ Trizact™ Cloth Belt 307EA uses proprietary microreplication technology where micron-graded aluminium oxide particles are formed into tiny pyramids of abrasive mineral and then coated on a rayon backing. These these pyramids wear, fresh and sharp mineral is continually exposes to produce a consistent cut and predictable, fine finish.

Features & Benefits:
• Self-sharpening pyramids start sharp, stay sharp, and run cooler than conventional abrasives
• Flexible backing flows over contoured surfaces for consistent finishing
• Ideal for intermediate finishing and fine polishing prior to plating or buffing
• Produces finer finishes than conventional electrostatically coated abrasives
