Water repellent. Anti Wetting.
Long lasting performance.

Aculon® has a variety of surface modification technologies capable of functionalizing numerous substrate types to be hydrophobic. Aculon’s® hydrophobic coatings and treatments are highly water repellent offering numerous performance benefits. In addition these coatings are ultra thin (nanoscale), optically clear and quite durable. Hydrophobic treatments from Aculon® will also act as an anti wetting coating solution. There are numerous performance advantages to having a hydrophobic surface on countless applications.

Does your product need a hydrophobic coating?

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

  • You're experiencing problems due to liquid behavior on the surface of your product.
  • Cleaning your surface is time consuming, expensive, or impossible.
  • Physical barrier to prevent liquid flow is not possible
  • Adhesive materials stick to surface
  • Water or oil droplets/contamination impede optical performance.
  • Exposure to water results in electronics failure.
  • Wettability of a surface or powder is not ideal

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.

Our hydrophobic technologies will yield a robust a long lasting hydrophobic surface. Typical water contact angles (measurement of surface energy) are in the 115°-120° range which is nearly super hydrophobic. These treatments are nanoscale, as thin as 2-4 nm thin 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 repellent carbon based molecule which can impart a durable hydrophobic surface on oxide containing substrates. Other hydrophobic options in our suite of technologies for modifying surfaces to be hydrophobic are organometallics, transition metal complexs & 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.

Application Process

Aculon hydrophobic 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.
