Diamond Spray – Practical Dosing

Diamond spray is the convenient alternative to suspension when fine, uniform distribution and easy dosing are required. We offer two bases: spray dispenser variant and alcohol-based for water-sensitive or corrosion-critical materials. Available in mono- or polycrystalline forms, in proven grit sizes and concentrations for reproducible results.

Key Features

• Two bases:
  • Spray dispenser variant: for automated dosing systems, optimized viscosity
  • Alcohol-based: ideal for zinc coatings, magnesium alloys, and other water-sensitive materials
• Precise dosing: fine spray distribution, consistent grit and concentration distribution
• Process reliability: stable removal rates from pre-polish to fine polish
• Flexible: mono- or polycrystalline depending on material and target surface
• Compatible: with common polishing cloths, lubricants, and polishing machines
• Economical: efficient application

Product Variants

• Spray dispenser variant
  • Developed for spray dispensers and automated dosing systems
  • Uniform aerosol distribution and reproducible dosing
  • Suitable for series processes and laboratory automation
• Alcohol-based
  • For water-sensitive and corrosion-critical materials (e.g., zinc coatings, magnesium)
  • Fast drying, low residues, reduced risk of corrosion
  • Higher effective removal rate due to thinner lubricant film

Crystal Type

• Monocrystalline: controlled scratch pattern, gentle on material – good for steels and non-ferrous metals
• Polycrystalline: self-sharpening, high removal rate – good for ceramics, hard metal, glass

Grit Sizes and Applications

• Coarse to pre-polish: 15–9 μm
• Standard polish: 6–3 μm
• Fine polish: 1–0.25 μm
• Final finish: 0.04 μm with OPS/alumina suspension as a subsequent medium
  Note: Please list available grit sizes and intermediate sizes according to your product list.

Concentrations and Containers

• Typical concentrations: e.g., 25–100 cts/L (standard: 50 cts/L)
• Containers: pump spray bottle
  Note: Present exact concentrations/containers according to your diamond suspension logic.

Application Recommendation

1. Pre-polish (15–9 μm) – for water-sensitive materials: alcohol-based
2. Polishing stages (6–3 μm) – spray dispenser variant for automated processes
3. Fine polish (1–0.25 μm) – fine, uniform spray dosing
4. Final finish (0.04 μm) – chemical-mechanical with OPS/alumina suspension
   Dosing note: For spray dispensers follow the manufacturer’s instructions; apply manually in a thin, even layer.

Material suitability (selection)

• Steels (low- to high-alloy), non-ferrous metals: mono- or polycrystalline
• Zinc coatings, magnesium alloys, Zn die-cast: alcohol-based recommended
• Hard metal, ceramics, glass: polycrystalline for high removal rate

Comparison to suspension format

• Spray: convenient distribution, highly automatable (spray dispensers)
• Suspension: maximum flexibility for manual application
  Important: Surface quality primarily depends on grit size, crystal type, cloth, and parameters, not on the application format.

FAQ

• When to use the spray dispenser variant vs. alcohol-based?
  • Spray dispenser variant: automated systems, reproducible cycle times
  • Alcohol-based: water-sensitive materials, fast drying
• Mono vs. poly?
  • Mono: controlled scratch pattern, more sensitive materials
  • Poly: high removal rate, self-sharpening
• Is the spray quality the same as with suspension?
  • Yes, with identical grit size/concentration. Differences lie in application/handling.
