Gentoo’s hydrophobic coating leaves no water trail.
The Gentoo coating retains 100% transparency.
Gentoo is UV resistant, abrasion resistant and flexible.
Gentoo Hydrophobic Coating
Gentoo is a new, innovative technology that creates a completely transparent, extremely durable hydrophobic coating that repels water and prevents corrosion. While there are many hydrophobic coatings on the market, none possess the transparency and extreme durability of Gentoo.
Gentoo hydrophobic coating is unlike traditional hydrophobic and superhydrophobic coatings with its unique ability to not only repel water, most oils and solvents but also with its significant abrasion resistance, durability and flexibility.
Gentoo succeeds where other coatings fall short and is truly the next generation of hydrophobic coatings.
Gentoo is for Commercial sale only.

As a viable alternative to superhydrophobic coatings, UltraTech/Luna have developed a hydrophobic coating that, while having a lower contact angle, still provides excellent water-shedding capabilities, but is based on a highly durable, mechanically stable, abrasion resistant, and clear matrix. The interaction of water with the surface of the Gentoo hydrophobic surface treatment is shown at right.
The ultra-thin (<5 µm), rapid-cure, single coat system is easily applied to previously-painted, bare metallic or polymeric surfaces using common application techniques such as flow coat, brush or spray. The coating is so thin and conformal in fact that it may also be considered a surface treatment technology. The high optical transparency of the hydrophobic coating will not alter the appearance of a coated object but will shed water, improve corrosion resistance, resist mechanical abrasion and impact damage, reduce salt accumulation, dirt retention, and weathering degradation of the object. The functionalities of this hybrid coating provide a mechanism for covalent bond formation between the coating and the substrate, resulting in superior adhesion to metallic, plated and painted surfaces. The formulation of the Gentoo coating produces a highly durable coating with excellent water-shedding capability and abrasion resistance.

Likewise, panels of Nitronic 50 stainless steel were coated with the durable hydrophobic coating and compared with a commercial superhydrophobic coating for abrasion resistance. Initially, the as-prepared Gentoo coating had a water contact angle of 110° compared to >150° for the commercial superhydrophobic coating. After reciprocal abrasion (Figure 1) with ScotchBriteTM abrasive pads, the superhydrophobic sample was degraded significantly and the Gentoo durable hydrophobic was unchanged under the same conditions. More importantly, the watershed angle of the commercial coating increased drastically after a small amount of abrasion, but the Gentoo coating watershed angle did not change significantly even after extensive harsh abrasion. This same result was observed when the test was performed pre and post an immersion soak in seawater.
Gentoo is virtually unaltered by abrasion, whereas Commercial coatings flake off and turn opaque.
The influence of chemical exposure on the contact angle was determined for various industrial chemicals commonly found in military depot settings. The chemicals investigated spanned a range of hydrocarbon, alcohol, polyalphaolefins, hydraulic fluid, deicing fluid, oils, salt water, cleaners, plastic polish and conversion coatings. As shown in Table 3, the majority of the chemicals did not have a significant influence on the contact angles of the hydrophobic coating, with < 2.1% reduction in contact angle after 48 hours of chemical exposure.
