3C Pyramid Structured Abrasive Sanding Disc | Foam Backed Trizact Type Sanding Disc for Automotive Refinishing
Consistent Cut. Predictable Finish. Lower Rework Cost.
This 3C pyramid-shaped sanding disc features structured abrasive technology and a multi-layer foam backing, delivering consistent cutting performance, uniform scratch patterns, and stable performance throughout its entire service life.
Product Overview
This pyramid-structured abrasive disc is designed specifically for fine and ultra-fine finishing stages, where surface uniformity is more critical than aggressive deburring. Its specially engineered micro-replicated abrasive structure ensures a uniform scratch pattern, thereby reducing polishing time and minimizing rework.Compared to traditional sandpaper, this structured abrasive disc maintains a consistent cutting rate, prevents deep and random scratches, and delivers predictable surface results on large areas and complex contours.
Construction & Materials
Structured Abrasive Layer
A precision-molded pyramid-shaped abrasive structure made from a high-quality mixture of aluminum oxide or ceramic. Achieves controlled and consistent cutting performance through self-renewing abrasion.
Film Backing
A high-strength film substrate provides excellent dimensional stability and heat resistance. Prevents edge curling and maintains contact with the surface during high-speed grinding.
Multi-layer foam transition layer
A high-density polyurethane foam transition layer absorbs pressure fluctuations. Ensures uniform contact, reduces the risk of over-grinding, and improves the consistency of surface finishing.
Hook-and-loop backing
Compatible with standard backing pads for quick replacement and secure attachment. Optimized to enhance efficiency in industrial grinding operations.
