Aculon Sapphire Repellency Treatment is extremely durable relative to competitive nanoscale repellent treatments. Unlike other technologies requiring surface microstructuring (inherently very fragile) Aculon's technology is a non-toxic chemical treatment which is covalently bound to the surface. Just how durable or how long will the treatment last? Well that depends on the part and application!
Aculon Sapphire Repellency Treatment is only 2-4 nm thick. It is covalently bound to the substrate and thus very stable. While it will reduce impact damage as the Aculon treatment make the surface lubricious and therefore more likely that impacts to glance off the surface, the treatment is too thin to add any direct scratch or gouge resistance or hardness to the part. A treated part will behave as normal (untreated) when exposed to a scratching/polishing/abrasive action. In other words if an action polishes, scratches, or abrades your untreated part (from here on out "impacts") it will do the same to your treated part, removing the treatment in the process. Fortunately, if a part that is damaged it can easily be retreated.
Aculon sapphire repellency Treatment is chemically resistant to nearly all liquid chemicals! See below for lists of compatible and incompatible materials:
Aculon Sapphire Repellency Treatment is impacted by UV over time. The level of degradation depends on exposure time & intensity. Anywhere from weeks to months before reapplication is required can be expected. Aculon Sapphire Repellency Treatment is not intended for outdoor applications where a permanent treatment is required.
Aculon Sapphire Repellency Treatment is stable to 250C before the chemical structure is damaged and performance impacted. There is no known lower temperature threshold which damages the treatment.
Parts Must be sufficiently clean prior to treatment for proper bonding and effective application. See "Cleaning" tab for more detail.
Apply Aculon Sapphire Treatment via dip bath to fully treat parts with a uniform treatment ensuring even coverage over entire part. Please note that this is only an option for custom applications. Contact us now to see how we can work to implement this solution into your facility.

A properly cleaned and prepared surface is imperative for Aculon Sapphire Repellency Treatment to properly bond with the surface and offer desired performance. The level of cleanliness can play a role in performance and durability/lifetime of the treatment. Cleaning Methods can be summarized into Good, Better, & Best Options. The below cleaning options assume that the part to be treated has been sufficiently degreased and cleaned of all visual contaminants first. The best results are achieved when a water break free surface is achieved (typically better & best).
Often times a good enough cleaning method is sufficient when your process needs to be simple and reapplication is not an inconvenience in the future. Good enough cleaning methods sufficiently clean the surface but do not necessarily achieve a water break free surface, which indicates a perfectly clean surface. Examples of good enough cleaning methods include:
When performance and durability are important or when reapplication is not practical and more reliable and efficient cleaning method is desired. Better options are designed to achieve a water break free surface (perfectly clean) in the vast majority of parts with many different contamination types. Better cleaning methods typically utilize more aggressive chemicals and may require rinsing or specific steps to ensure proper results. Examples of "better" cleaning methods include:
When performance and durability are critical and reapplication is absolutely not practical the absolute best cleaning options are required. These options are designed to achieve a uniform water break free surface (perfectly clean) reliably on all parts. These Best cleaning methods utilize more aggressive chemicals requiring rinsing and specific steps to ensure proper results. In some cases physical cleaning methods are utilized. Examples of "best" cleaning methods include:

How thick is the treatment?
How do you know it is only 2-4 nm thick?
Via XPS and other sensitive optical measurements such as ellipsometry we can quantitatively confirm thickness. The treatment is a self limiting reaction which does not cross link, so we know the thickness is limited to the chemistries molecular chain length
Can I see the treatment?
No, it is 100% optically clear. Minus the change in performance your properly treated part will look exactly the same.
100% clear? Really? There must be some reflected or absorbed loss?
Yes 100% clear, 100% transmission with no reflected or absorbed losses. Spectral reflectance can not detect the coatings presence on the surface.
Do I need to clean the part? It looks clean enough.
Yes, to get a properly performing coating it must be cleaned no matter how it looks just prior to treatment. Unseen organic and inorganic contaminants can prevent bonding. Atmospheric contaminants will quickly contaminate a part that has been left to sit.
How do I know if the part is 100% clean?
It is water break free. Note that "good" cleaning options may not clean to this level.
Is it superhydrophobic? (contact angle 150 degree plus)
No, while very hydrophobic (and also oleophobic), it is not technically superhydrophobic. Although the term "superhydrophobic" has somewhat taken over nomenclature, a durable superhydrophobic coating is a unicorn, it does not exist. Current superhydrophobics rely on surface microstructuring and while impressive at first (you've have seen the youtube videos) are extremely fragile and offer terrible longevity (now go check the Amazon reviews of these products). We have found that hydrophobic coatings are sufficient for 95% of our clients' applications.
Is it Oleophobic?
Yes! Aculon Sapphire Repellency Treatment repels oils with oil contact angles in the 80-90 degree range.
Will you sell me a smaller amount to treat my sunglasses or car windshield?
Sorry, but at this time Aculon is a business to business company and is only working on commercial accounts and is not supporting consumer requests.
Is it possible to over apply the treatment?
No, the treatment is a self limiting reaction and does not crosslink to form thicker layers.
