The 3M Diamond Lapping Film Discs with Pressure-Sensitive Adhesive (PSA) Back are engineered for precision lapping and polishing of metal, glass, and ceramic surfaces. These discs combine resin-bonded diamond abrasive with secure PSA attachment for controlled, repeatable finishing across a broad range of micron sizes, concentrations, and coatings.
Key Features:
- Backing: Pressure-Sensitive Adhesive (PSA) over Non-Adhesive (NH) base for secure attachment to backing pads
- Abrasive: Diamond, available across multiple micron sizes, concentrations, and coatings, size-dependent (see configuration table below)
Benefits:
- Secure, No-Slip Attachment: PSA backing bonds directly to the backing pad for stable performance during lapping
- Superior Cutting Power: Resin-bonded diamond abrasive delivers efficient material removal and a long service life
- Precise, Repeatable Results: A wide range of micron sizes, concentrations, and coatings supports precise control over lapping and finishing outcomes
- Efficient Setup: Peel-and-apply attachment reduces changeover time between discs
Applications:
- Lapping and polishing metal, glass, or ceramic surfaces
- Preparing surfaces for optical components
- Smoothing and leveling materials
- Achieving precise tolerances and finishes
