Overview
Polycrystalline Diamond Spray
What This Product Is
Polycrystalline diamond spray delivers a polycrystalline diamond suspension in a spray applicator, for metered, even cloth charging. The diamond particles are clusters of many small crystals with a self-sharpening action, giving high material removal and a fine finish — combined here with the convenience and consistency of spray application. It is supplied ready to spray.
Intended Use in Metallography
Used for intermediate and fine polishing, selected when:
- Polishing hard or mixed-phase materials that benefit from polycrystalline diamond
- Fast, even, metered recharging of the cloth is wanted
- Higher removal with a fine finish and low subsurface deformation is the goal
Typical Applications
Commonly used for:
- Hardened and tool steels
- Carbides, cermets, and wear-resistant materials
- Ceramics and composites
Beyond metallography, polycrystalline diamond spray is also used in:
- Petrography of hard minerals
- Ceramics and advanced or composite materials
- Optics and glass finishing
- Tool, die, and mold finishing
When This Product Is NOT Ideal
- For soft, ductile metals prone to smearing
- When a paste or suspension better suits the process
- When a single-crystal (monocrystalline) diamond is specified
Where This Fits in the Preparation Process
- After grinding
- Before an oxide final polish, when required

Frequently Asked Questions
What are the advantages of a polycrystalline diamond spray?
It combines polycrystalline diamond's high removal and fine finish on hard, mixed-phase materials with the convenience of metered, even cloth charging and reduced waste.
Does the polycrystalline spray come in water- or oil-soluble?
It is supplied ready to spray in a single formulation — see the product options for available micron sizes and bottle sizes. For a choice of water- or oil-soluble carrier, the monocrystalline spray and the diamond compounds offer that selection.
How does a spray recharge the cloth?
A short, even burst deposits a metered amount of diamond onto the polishing cloth, so recharging is fast and consistent during the cycle.
Can polycrystalline diamond spray be used outside metallography?
Yes. It polishes hard materials across petrography, ceramics and advanced materials, optics and glass, and tool and die finishing. Its self-sharpening diamond suits hard, wear-resistant work, with spray application adding convenience.
