Precision Coated Diamond Abrasive Lapping Film
NanoKem incorporates a proprietary new particle, designed to improve the quality of polished surfaces by eliminating scratch-generating agglomerations. By polishing at nominal particle sizes it shortens polishing processes and enables increased cutting from each diamond particle. One-step NanoKem film achieves the end finish specification of as many as two or three conventional diamond film products.

Scratch-free finishing in one step - the previous carbide surface after polishing with 1 micron NanoKem film
Key benefits:
- Performance quality: the most achievable fine finish using coated abrasives
- Cost savings: elimination of production process steps
- Safety/environmental improvements: elimination of dirty, messy slurries
