Diamond Polishing Materials

Diamond Sticks

The Diamond Stick is mainly used for manual polishing.
The polishing cloth resorbs the diamonds from the diamond stick very quickly.
The handling is easier than in the case of a paste and the diamond stick can also be used while the polishing wheel rotates.
Our Diamond Stick can be used with water-, glycol- and alcoholic-containing lubricants. It contains less than 0.1% water and therefore it is perfect for water-free preparation.
The high diamond concentration of 250 ct / l ensures a high removal rate.


Diamond paste

The diamond paste has a very high diamond concentration, 500ct / l. Even with using a small amount of this paste you can reach a high material removal. This is ideal for polishing of the mobile component examination.

- Poly- and mono-crystalline
- In grain sizes 45, 25, 15, 9, 6, 3 and 1 µm, polycrystalline additional in 0.25 and 0.1 µm
- 10 g spraying device


Diamond suspensions are used a lot these days, because of the widespread automation of sample preparation, the preferred medium for the dosage of diamonds.

Our suspensions are developed according to the following aspects:

- Environmental friendliness
- Reproducible results
- Short preparation time
- Diamond suspension Poly 0,1 µm, 0,25 µm, 1 µm, 3 µm, 6 µm, 9 µm and 15 µm
- Diamond suspension Mono 1 µm, 3 µm, 6µm, 9 µm und 15 µm
- Package sizes: 250 ml, 1 liter und 2,5 liter

Diamond suspension Mono Plus and Poly Plus at least twice as high diamond concentration. This is a low-cost alternative compared with the diamond suspension Poly

- Perfect preparation results with the new Clear Lubricant +!

Diamond suspension water-free - especially suitable for the preparation of water-sensitive materials - customer feedback: excellent!

In addition we offer diamond suspensions mono and poly alcohol-based:

- Diamond suspensions poly alcohol-based  0,25 µm, 1 µm, 3 µm, 6 µm, 9 µm and 15 µm
- Diamond suspensions mono alcohol-based  1 µm, 3 µm, 6µm, 9 µm and 15 µm
- Package sizes: 250 ml, 1 liter in Poly, 1 liter in Mono

Two-in-One diamond suspensions:

CT DiaTwin Mono und Poly

CT DiaTwin Max Mono and Poly with at least twice as high diamond concentration!

CT DiaTwin Poly water-free - especially suitable for the preparation of water-sensitive materials - customer feedback: excellent!

For all CT DiaTwins:

- Time saving in the preparation is up to 50 %!
- Dosage one liquid only, instead of two, suspension and lubricant.

CT DiaTwin is a ready mix of lubricant and suspension, permanently stable, so that reproducible results are guaranteed. The increased removal of our lubricant was retained completely, so you can expect up to 30 - 50% shorter preparation times  (CT DiaTwin Poly). Use our practical pump spray bottle for perfect manual dosage. Also available with automatic dosing system for lubricants. This saves room for several grain sizes.

  • Short preparation time
  • Reproducible results
  • Full flexibility; adjust the diamond concentration with extender or suspension
  • Little impact of overdose
  • Water-based, no labeling obligation
  • Biodegradable

The complete program:

Based on our lubricant and suspensions we have developed a combination product that makes the dosage very easy. All grain sizes, mono- and polycrystalline, are also available as CT DiaTwin.
Unlike other mixing products CT DiaTwin adapts to the surface. So you need no separate CT DiaTwin for polishing and grinding surface, but one can be content with the usual grain sizes.
Unlike other 2-in-1 products CT DiaTwin contains pure mono- or polycrystalline diamonds.
Diamond concentration customize
CT DiaTwin is with our suspensions and extenders completely compatible, so you can customize CT DiaTwin if you want to change the properties. Dilute with extender, or increase the concentration of diamond by adding diamond suspension.
Small effects of overdose
Because of the low viscosity of the lubricating film, the excessive DiaDoublo spreads quickly to the bedding layer. This reduces the hydroplaning effect and the negative effects of an overdose are limited to an increased consumption.
Environmental friendliness
CT DiaTwin is prepared with a preservative system that is gentle to the skin. It is free of boric acid, amines and nitrite. CT DiaTwin also contains no additives of chlorine- and sulfur-base.
Reproducible results
Many factors become important, if short preparation time and reproducibility is expected.
Permanent floating diamonds
CT DiaTwin keeps the abrasive in a homogeneous mixture in suspension. If the diamonds start to sink to the ground, the dosage and the size of the diamonds begin to vary, while the bottle is emptied gradually. The consequences are varying polish results. Both the removal of material and the crack samples vary, as all diamonds sink to the ground, but the heavy (large) diamonds first. Our CT DiaTwins keep the diamonds permanently floating and therefore the polishing results are the same every time.
Uniform diamond with a uniform geometry
The conditions to achieve this are similar, almost cubic shaped diamond. Therefore significantly different geometries such as needle shapes or flakes are minimized.
Controlled suspension
Small particles - the same goes for diamonds - have a tendency to form aggregates, if the suspension process is not performed correctly. We control the product and ensure that our specifications are maintained.
Short preparation times - Low grain size distribution
If durable abrasives such as diamonds are used, it is important that the grain size distribution is bounded as much as possible. Large particles scrape stronger and they cause a longer preparation time. Small particles have not the necessary removal so that they extend the current preparation phase. Therefore, we use the most strictly sorted diamonds, which are commercially available. Each batch is sorted rigorously and the variation from batch to batch is minimal.
The diamond concentration of CT DiaTwin poly comes up to a mixture of suspension and lubricant of 1:2, in order to combine high abrasion with optimal surface.
CT DiaTwin Mono has a concentration corresponding to a mixing ratio of 1:3, to obtain a good efficiency.
CT DiaTwin poly,CT DiaTwin Max poly, CT DiaTwin mono and CT DiaTwin Max mono are available in
1 µm, 3 µm, 6 µm, 9 µm and 15 µm.
Package size: 500 ml and 5 liter


Diamond Sprays

The diamond spray has replaced the paste almost completely. There have been many attempts to produce better and more effective suspensions, but the combination of diamond spray and an alcohol-based Lubricant is still considered the best alternative.

Our spray is developed to:

  • Reproducible results
  • Short preparation time
  • Water-free polishing
  • Environmental friendliness

Environmental friendliness

The spray consists of ethanol (99.9%), diamonds and environmentally friendly CO2, that instead of the normally used butane-propane mix, which is actually a lighter gas, is used as a propellant gas. The ethanol evaporates quickly and the diamonds are freely accessible. The spray is the dosage form with the most effective removal.

High concentration

The material removal is increased together with the growing concentration of diamonds, but only up to a certain limit. A further addition of diamonds has only a low effect on the removal. All our diamond sprays have a concentration of 26.5 ct/l.


The products contain less than 0.1% water. Therefore, the spray can be used very well with the Lubricant Blue, if you need a water-free polishing. te enthalten weniger als 0,1 % Wasser.

NFG-Diamond spray poly and mono!

The alternative to the traditional diamond spray - no compressed air. Therefore, not flammable, but with the same properties and with higher diamond concentration (30 ct/l instead of 26.5 ct/l)!

Diamond spray poly: 0,25 µm, 1 µm, 3 µm, 6 µm, 9 µm und 15, Package size: 150 ml
Diamond spray Mono 1 µm, 3 µm, 6 µm, 9 µm und 15 µm
