Diamond Polishing Paste & Compound for Precision Surface Finishing
Crownkyn diamond polishing paste is designed for precision finishing of molds, dies, cutting tools and hard material components where controlled polishing performance and fine surface quality are required.
Available with monocrystalline, polycrystalline and agglomerated diamond options. Particle size, concentration and carrier system can be customized according to your material, polishing process and surface finish requirements.
What Is Diamond Polishing Paste?
Diamond polishing paste is a concentrated diamond abrasive formulation designed for controlled polishing and fine surface finishing. Unlike liquid diamond slurry, paste provides better handling control for manual polishing and localized finishing areas.
It is commonly used for mold cavities, dies, cutting tools and precision components where surface quality, dimensional control and polishing consistency are critical.
Diamond paste is preferred for applications requiring precise polishing control, good lubrication and high-quality surface finish.
Diamond Paste Formulations by Diamond Type
Crownkyn supplies monocrystalline, polycrystalline and nano diamond paste formulations for different removal rates, surface finishes and precision polishing requirements.
Monocrystalline Diamond Paste
General Polishing GradeMonocrystalline diamond paste uses strong single-crystal particles with defined cutting edges for efficient material removal and repeatable polishing of hard materials.
Polycrystalline Diamond Paste
Fine Finishing GradePolycrystalline diamond paste uses multi-edged particles with controlled micro-fracture to renew cutting points, reduce scratch depth and produce a finer surface finish.
Nano Diamond Paste
Ultra-Fine Polishing GradeNano diamond paste contains ultra-fine diamond particles formulated for final polishing stages requiring very low roughness, fine abrasive distribution and minimal surface damage.
How to Choose Diamond Polishing Paste?
Selecting diamond paste depends on the workpiece material, polishing goal, diamond type and carrier system.

Common questions about diamond polishing paste selection, applications and customized formulations.
What is diamond polishing paste used for? +
Diamond polishing paste is mainly used for precision finishing of molds, dies, cutting tools and hard materials. It provides controlled material removal and fine surface finishing for applications requiring smooth and consistent results.
What is the difference between diamond paste and diamond slurry? +
Diamond paste is a high-viscosity abrasive formulation mainly used for manual polishing and localized finishing. Diamond slurry is a liquid suspension designed for lapping machines, automated dispensing and continuous polishing processes.
Which diamond paste is suitable for mold polishing? +
The suitable diamond paste depends on the polishing stage. Monocrystalline diamond paste is commonly used for efficient material removal, while polycrystalline and agglomerated diamond pastes are preferred for fine finishing and reduced surface scratches.
How does diamond particle size affect polishing performance? +
Diamond particle size affects material removal rate, scratch depth and final surface quality. Larger particles provide faster cutting action, while smaller particles are used for fine finishing and mirror-like surface requirements.
What grit sizes are available for diamond polishing paste? +
Diamond polishing paste is available from submicron to micron particle sizes. Common grades include 0.25 μm, 0.5 μm, 1 μm, 3 μm, 6 μm and 9 μm. The suitable particle size depends on the workpiece material, polishing stage and required surface finish.
Can Crownkyn customize diamond polishing paste? +
Yes. Crownkyn can customize diamond paste formulations based on diamond type, particle size, concentration, carrier system and viscosity requirements. Recommendations can be provided according to your material and polishing process.
