Mono & Polycrystalline DiaDoublo Diamond Suspensions

Mono- and Polycrystalline 45 µm to 0.025 µm

Dosing of only one liquid, instead of both suspension and lubricant. DiaDoublo is a ready mix of lubricant and suspension, it is permanently stable and thus ensures reproducible results.

The increased removal rate provided by our lubricants has been fully retained; you may therefore allow for a 30-50% shorter preparation time (DiaDoublo Poly).

· Quick preparation
· Adjust diamond concentration with extender or suspension
· Little effect of overdosing
· Reproducible results
· Water-based, no hazard warnings
· Biodegradable
· Water-free version

Full Range

Based on our lubricants and diamond suspensions , we have formulated a combination product, which makes dosing as easy as can be. All grain sizes in both mono- and polycrystalline diamonds are available as DiaDoublo.
Contrary to competing two-in-one diamond suspensions; DiaDoublo is perfectly compatible with any polishing or fine-grinding surface, thus you can work with the usual micron sizes.

DiaDoublo contains solely mono- or polycrystalline diamonds.

Adjustable diamond concentration

DiaDoublo is fully compatible with our diamond suspensions and Extender consequently you can adjust DiaDoublo if you wish to change its performance. Dilute with extender, or increase the diamond concentration by adding diamond suspension.

Limited effects of overdosing

As a result of the lubricating film’s low viscosity, excessive liquid is quickly dispersed on the surface. This reduces the aquaplaning effect, and the disadvantage of overdosing is limited to an increased consumption.

Water-free

DiaDoublo Water-free is made from the same mix of glycols as Aka-Paste, thus it is non-toxic and non-flammable. It contains less than 0.1% water and is perfect for preparation of water sensitive specimens. The viscocity is higher than our water based DiaDoublo, therefore DiaDoublo Water-free can only be dosed using peristaltic pumps. The scratch depth is deeper than the waterbased DiaDoublo, so force on the specimens should be lowered with 50 - 70 % to get the same scratch depth.

Reproduceable results

Many factors are involved when seeking short preparation times as well as reproducibility of the preparation. Here are the ones we have in focus.

Permanently suspended diamonds

Suspensions keep the abrasives suspended in a homogenous mixture. If the diamonds were to settle out, it would cause a variation in both concentration and size of the diamonds as the bottle is gradually used, causing a variance in polishing results. Both material removal rate and surface finish would vary because the diamonds would settle out on the bottom, starting with the heavy (larger) diamonds.

DiaDoublo keeps the diamonds permanently suspended, insuring consistent polishing results every time.

Uniform diamonds with uniform geometry

The decisive factor in achieving uniform particle size distribution is to use uniform, almost cubic-shaped diamonds. Therefore, the presence of deviating geometry, such as needle-shaped crystals or flakes, has been minimized.

Narrow batch tolerance

Our diamonds are graded into very narrow particle size distributions with a very narrow standard tolerance. Variances are minimized from batch to batch. Take a look at our specifications.

Controlled slurring

Small particles, diamonds included, have a tendency to agglomerate if the slurry process is not conducted correctly. We inspect every batch to ensure it meets our specifications.

Quick preparation

DiaDoublo is formulated on the basis of our lubricants Aka-Lube, ensuring a high removal rate and perfect scratch pattern, right from the start. But there are other factors that also matters.

Narrow particle size distribution

When using the hardest wearing abrasives like diamonds, it is important that particle size distribution has the narrowest deviation possible. Large particles will result in deep scratches and require longer preparation times in the subsequent step, and small particles will not provide the required material removal rate, thereby prolonging the ongoing preparation step. We therefore use the most stringently graded diamond particles commercially available.

Modern sorting technology, combined with electronic and optical quality control, ensures highly reproducible preparation results. See our close tolerance at specifications

High diamond concentration

Polycrystalline DiaDoublo has a concentration of 6.7 ct/l, equivalent to a mixing ratio between suspension and lubricant of 1:2. This ensures a combination of high removal rate and perfect scratch pattern.
Monocrystalline DiaDoublo has a concentration of 5 ct/l, equivalent to a mixing ratio between suspension and lubricant of 1:3, for good economic preparation.

Environmental friendly

Water based, no hazard warnings
Just like our diamond suspensions DiaDoublo is formulated with an eye to our environment. In fact it does not even contain a preservative. By carefully selecting the used components, we have managed to make at system that does not support the growth of bacteria.

Specifications

Are you getting this detailed information from you present supplier?
DiaDoublo is a technical product, and should be supplied with as detailed specifications as necessary.
We use the best sorted diamonds commercially available. Hence we have nothing against sharing this information; you will not be able to get anything better anywhere.
Our mono- and polycrystalline diamonds are sorted to the same specifications. Make your own test, what is best in you application, mono or polycrystalline?
