How it Works


Aculon® has a wide variety of coating 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.

Hydrophobic Performance

Our hydrophobic coating 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 nano-coatings 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 surface coating every time!

Technology - Hydrophobic Coating Platforms

Aculon’s® core coating 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 coated surface on oxide containing substrates. Other hydrophobic options in our suite of technologies for modifying surfaces to be hydrophobic are organometallic, transition metal complex, & surface growth polymer coatings.

Hydrophobic Surface Durability

Aculon’s® hydrophobic surface coatings are chemically robust with options that can withstand most any environment or exposure condition. These nano-coatings 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 hydrophobic treatment is “as strong as the underlying substrate”. If your substrate will survive the environment undamaged, our hydrophobic coatings will too.

Application Process - Hydrophobic Nano-Coatings

Aculon’s® hydrophobic nano-coatings are robust and scalable for high volume commercial applications. These coatings and 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.
