Water Attracting. Water Wetting. Long Lasting Performance.

Aculon® has a variety of surface modification technologies capable of functionalizing numerous substrate types to be hydrophilic. Aculon’s® hydrophobic coatings and treatments are highly water attracting offering numerous performance benefits. In addition these coatings are ultra thin (nanoscale), optically clear and quite durable. There are numerous performance advantages to having a hydrophilic surface on countless applications.

Does your product need a hydrophilic coating?

Hydrophilic surface modification technologies can be used to address a wide variety of problems. Some examples below where a hydrophilic coating will help improve the quality of your product.

  • Functional Issue due to liquid behavior on surface
  • Surface contamination (fingerprints) degrades a products aesthetic behavior
  • Water droplets/contamination impede optical performance
  • Water droplets results in optical issues on lenses and camera domes
  • Surface is not lubricious enough
  • Wettability of a surface or powder is not ideal
  • Desire to prevent bubble formation underwater

How it Works


Aculon has a wide variety of technologies at our disposal meaning that we can treat nearly any surface or substrate. This includes, but is not limited to metals, polymers, semiconductors, ceramics, and glass. The type of substrate will impact the technology options which can be utilized in addition to cleaning or other processing steps that may be required. In general due to the presence of a surface oxide layer we find the highest likelihood of success with metals, ceramics, glass, and semiconductors.

Substrates suitable for surface modification - plastic, metal, glass, and circuit boards
Hydrophilic technology performance in action


Our hydrophilic technologies will yield a robust and long lasting hydrophilic surface. Typical water contact angles (measurement of surface energy) are in the <10° range.. These treatments are predominantly nanoscale, as thin as 2-4 nm in thickness leaving your part visually unchanged and optically clear. A self assembling process ensures a uniform and even treatment every time!


Aculon's core technology is based around the SAMP or "Self Assembled Monolayer of Phosphonates" which is comprised of a phosphonic acid and a functional tail molecule which can impart a variety of surface behaviors on oxide containing substrates. Other hydrophilic options in our suite of technologies for modifying surfaces to be hydrophilic are organometallics, transition metal complexs, traditional polymeric coatings, & surface growth polymers.

Treatments are chemically robust with options that can withstand most any environment or exposure condition. Treatments are thermally stable (200°-300°C+) in ambient air. Due to strong covalent bonding they are also resistant to abrasion. We have a saying that the treatment is “as strong as the underlying substrate”. If your substrate will survive the environment undamaged, our coatings will too. We also have hydrophilic options which are more durable to abrasion than the underlying substrate!

Application Process

Aculon hydrophilic treatments are robust and scalable for high volume commercial applications. Treatments are all applied via wet chemical processes, meaning no deposition equipment, chambers, or batch processing, ever! Application options include spray, wipe, dip, jet, or dispense.
