Abrasive Media Selection Guide

• 3M™ Trizact™ (Microreplication Technology): Microscopic pyramids of micron-graded aluminum oxide continually wear away to expose fresh mineral. Maintains uniform cut rates, cooler running temperatures, and predictable fine finishes prior to plating or final buffing.
• Non-Woven Nylon Web: Elastic three-dimensional web removes heat tint, surface scratches, and light burrs, imparting a clean, uniform satin/brushed finish without undercutting or smearing.
• Seamless Pure Wool Felt: Low-stretch, jointless endless design engineered for use with diamond slurries, green rouge, or polishing pastes to produce flawless mirror finishes on stainless steel tubing, knife blades, and precision parts.

Key Characteristics

• Predictable Finish Progression: Transition seamlessly from Trizact prep to non-woven satin conditioning to wool felt mirror polishing.
• Cool Running on Heat-Sensitive Steels: Microreplicated pyramids and open-web structures minimize heat transfer, preventing workpiece warping or blue discoloration.
• Durable & Flexible Backing: Conforms smoothly to curved contours, knife bevels, and cylindrical tubing.

Recommended Applications

• Custom Knife Making & Cutlery: Pre-buffing bevel finishing, satin blade conditioning, and mirror polishing on hardened cutlery steel.
• Stainless Steel Pipe & Tube Fabrication: Blending weld joints, removing oxidation, and restoring architectural satin/mirror finishes.
• Hardware & Machinery Component Polishing: Precision deburring and surface preparation prior to electroplating or anodizing.
