Multi-Surface Hydrophobic Treatment

Aculon®, an award-winning & proven supplier to numerous industries, introduces Aculon® Multi-Surface Hydrophobic Treatment, the best-in-class repellency technology. Aculon® multi surface hydrophobic technology is designed to make many surfaces including plastics, rubber, fabrics,and painted surfaces, hydrophobic, and repellent to water and other water based fluids. Aculon® Multi-Surface Hydrophobic treatment is easy to apply, optically clear and ultra thin. It can even be applied via several application methods. Features include:

  • Hydrophobicity
  • Uniform Thickness
  • Repel Most Aqueous Liquids
  • Optically Clear (100% transmission)
  • Apply via Dip, Wipe, or Spray
  • No Capital Equipment
  • Apply in Minutes
  • Easily reapplied in field if damaged


Aculon® Multisurface Hydrophobic Treatment typically imparts inital water contact angles of around 110 degrees. After significant abrasion cycles, these contact angles are only slightly affected. This technology results in a hydrophobic coating that can be applied to nearly all surfaces.

Aculon® Multi-Surface Hydrophobic Treatment is relatively durable relative to competitive nanoscale repellent treatments. Unlike other technologies requiring surface microstructuring (inherently very fragile), Aculon® technology is a non-toxic chemical treatment which physically adsorbs onto the surface. It does not covalently bond however so it is not meant to be permanent! Just how durable or how long will the treatment last? Well that depends on the part and application! Depending on the exposure conditions a lifetime of days to years can be expected!

Note that, in most cases, Aculon® Multi Surface Hydrophobic Treatment is intended to be a temporary treatment where re-application is acceptable. You should test to determine the lifetime of the treatment on your particular application to determine a reapplication schedule.

Abrasion Resistance

Aculon® Multi-Surface Hydrophobic Treatment ranges from 10-500 nm thick depending on application method. It is physically 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. The lifetime will depend on the applied thickness of the coating (see application methods) and the abrasive action. Reapplication may be needed after a few days in aggressive environments and may never be needed on parts that see zero abrasion.

Chemical Resistance

Aculon® Multi-Surface Hydrophobic Treatment is chemically resistant to many liquid chemicals! See below for lists of compatible and incompatible materials:



  • Organic Solvents
    • Acetone
    • IPA
    • Petroleum
    • Etc
  • Neutral Aqueous Solvents (up to pH 9)
  • Acidic Solvents which do NOT etch your substrate

Not Compatible

  • Caustic Aqueous Solvents (pH 10+)

UV Resistance

Aculon® Multi-Surface Hydrophobic 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® Multi-Surface Hydrophobic Treatment is not intended for outdoor applications where a permanent treatment is required.

Temperature Resistance

Aculon® Multi-Surface Hydrophobic 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.

How to Apply

Step 1: Clean

Though beneficial, cleaning is typically not required for this technology. See cleaning tabs for options should you wish to prepare the surface with cleaning.

Step 2: Primer

Option – Dip

Apply Aculon® Multi-Surface Hydrophobic Treatment via dip bath to fully treat parts with a uniform treatment ensuring even coverage over entire part. Contact us now to see how we can work to implement this solution into your facility.

Typically results in treatment thickness of 5-40 nm depending on process parameters.

Option – Wipe

Apply Aculon® Multi-Surface Hydrophobic Treatment via an easy to apply wipe. Aculon® Multi-Surface Hydrophobic Treatment can be packaged in convenient pre-moistened wipes.

Typically results in treatment thickness of 20-100 nm depending on process parameters.

Option – Spray

Apply Aculon® Multi-Surface Hydrophobic Treatment via spray gun. Utilize common paint spray equipment for application.

Typically results in treatment thickness of 50-500 nm depending on process parameters.


Water break free surface for cleaningUnlike most of Aculon® other treatment technologies a properly cleaned and prepared surface is not required for application of Aculon® Multi-Surface Hydrophobic Treatment. In most cases a degreased and visually clean surface is acceptable. However in some cases cleaning may provide better and more durable performance. 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 future reapplication is not inconvenient. 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:

  • Windex
  • IPA
  • Other Solvent Degreasers


When performance and durability are important or when reapplication is not practical a more reliable and an efficient cleaning method is necessary. Better options are designed to achieve a water break free surface (perfectly clean) on the vast majority of parts against a variety of different contaminations. Better cleaning methods typically utilize more aggressive chemicals and may require rinsing or specific procedures to ensure proper results. Examples of “better” cleaning methods include:

  • Aculon® 905 (Room Temp Caustic cleaner)
  • Ceria polish (abrasive scrub)
  • Comet abrasive (or other polishing compound)


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. Care should be taken when using these methods as they are potentially hazardous to the operator and part to be coated. Examples of “best” cleaning methods include:

  • Aculon® 907 (Heated Caustic cleaning dip)
  • Argon Plasma
  • Corona Discharge
  • Piranha bath (H2SO4/H2O2)

How thick is the treatment?
5-500nm depending on treatment type and application parameters:

  • Dip : 5-40 nm
  • Wipe: 20-100 nm
  • Spray: 50-500 nm

How do you know the thickness?
Via Spectral Reflectance measurement techniques we can quantitatively confirm thickness after application.

Can I see the treatment?
It is 100% optically clear if applied uniformly and thinly. When applied at thicker levels and variable uniformity it is possible to see the presence of the treatment. Visible defects can usually be eliminated via buffing with a microfiber cloth.

Do I need to clean the part? It looks clean enough.
It is always a good idea to clean the substrate prior to application of our coatings. However, it is less important with the Multisurface Hydrophobic Treatment.The need for cleaning will depend on your process, part and durability requirements.

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, it is not superhydrophobic. In fact, at the moment a durable superhydrophobic treatment is a unicorn, it does not exist. Current superhydrophobics rely on surface microstructuring and while impressive at first (I know you have seen the youtube videos) are extremely fragile and offer terrible longevity (now go check the Amazon reviews of these products).

Is it oleophobic (oil & solvent repellent)?
No, this treatment is not oleophobic as it does not contain the necessary materials for repelling oil. Please utilize Aculon®
Multi Surface Oleophobic Treatment if an oleophobic treatment is required.

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 can be effectively applied at thick and thin levels.
