NEI Products » Protective Coatings » Superhydrophobic Coatings
NEI’s line of Superhydrophobic and Hydropobic coatings provide durable protection from abrasion and liquids and can be applied to a variety of substrates, including plastics, metals, glass, painted surfaces, fabrics, and 3D printed parts.
Our NANOMYTE® coatings are applicable to industrial condensers in general and, more particularly, surface condensers in power plants. The durable hydrophobic coatings can also be used to impart anti-fouling and easy-to-clean properties to the metallic surfaces of a variety of commonly used consumer products, such as kitchen appliances, shower heads, and hand rails, to name a few.
NEI’s Superhydrophobic and Hydrophobic coatings come in three different formulations:

SuperCNTM is a durable, highly hydrophobic coating originally designed for metal surfaces, but can also be used on a variety of other surfaces, including plastics, glass, painted surfaces, and fabrics. The patent-pending coating has a unique combination of properties that includes hydrophobicity and oleophobicity, with specifically good adhesion to stainless steel, superior abrasion, and erosion resistance. While the coating was originally developed for promoting dropwise condensation on stainless steel condenser tubes to enhance heat transfer efficiency, it can also be used to impart anti-fouling and easy-to-clean properties to other metallic surfaces, such as brass and titanium.
NANOMYTE® SuperCN is a two-part coating solution and can be applied by dipping, flowing, spinning, rolling, spraying, gravure and reverse gravure. For applications where a primer is necessary (such as polymer substrates), NEI supplies a primer product – NANOMYTE® SR-Primer – which works well with a range of plastics.
Ensure surfaces to be coated are clean and dry – the surfaces should be water-break free before coating application. The coating can be applied with or without the use of a primer depending on the substrate. NEI supplies a primer product, NANOMYTE® SR-Primer, which works well with a range of plastics. The primer may be applied by dipping, flowing, spinning, rolling or spraying.
For spray application of the primer, an HVLP spray gun with a nozzle size of < 1.0 mm is recommended, and the pressure should be set at approximately 25 to 30 psi. The primed parts should then be dried at 70ºC for 10 min before application of NANOMYTE® SuperCN.
It is recommended that coating application be performed in a clean environment to minimize surface defects. To make the coating solution, in a dust-free container combine Part A and Part B using the following ratio: 3:1 (A:B) in weigth. Mix well by stirring briefly (avoid vigorous stirring to minimize foam formation). The coating may be applied immediately after mixing by dipping, flowing, spinning, rolling or spraying.
For spray application of the coating, an HVLP spray gun with a nozzle size of < 1.0 mm is recommended, and the pressure should be set to approximately 25 to 30 psi. For best coating performance, use the coating solution within 24 hours after mixing, or store the mixed solution in a freezer for later use. If stored in freezer, warm the solution up to room temperature before application.
NANOMYTE® SuperCN is thermally cured at an elevated temperature. Recommended curing conditions:
Shorter cure times / reduced temperatures may also be used depending on surface properties and performance requirements;
test samples for desired performance when deviating from recommendations.
For complete specifications and application instructions, please refer to the Technical Data Sheet.
Appropriate personal protective equipment should be used at all times. Avoid contact with eyes, skin and clothing. Provide good ventilation or extraction and avoid prolonged or repeated breathing of vapor. Keep away from heat, sparks, flames and other sources of ignition. Wash hands thoroughly after handling.

SuperCN Plus is a functionally graded coating that imparts superhydrophobic properties to the underlying substrate while providing greater abrasion resistance compared to existing superhydrophobic coatings. Surfaces treated with SuperCN Plus force liquids to bead up and roll off, shedding water instantly and leaving the surface completely dry. SuperCN Plus can be applied to a variety of substrate materials, including plastics, metals, glass, painted surfaces, and fabrics.
NANOMYTE® SuperCN Plus is a single component coating solution and can be applied by dipping, flowing, spinning, rolling, or spraying. For applications where a primer is necessary (such as polymer substrates), NEI supplies a primer product – NANOMYTE® SR-Primer – which works well with a range of plastics.

For best coating performance, use the coating solution within 24 hours after mixing, or store the mixed solution in a freezer for later use. If stored in freezer, warm the solution up to room temperature before application.
It is recommended that coating be applied with an HVLP spray gun or an air brush in a well-ventilated spray booth. Shake the solution to mix well before coating application. For HVLP spray gun, a nozzle size of < 1.0 mm is recommended, and the pressure should be set at approximately 25 to 30 psi. Apply one or two uniform coats (no drying in between) to achieve a superhydrophobic surface.

WaterOFF!TM is an engineered coating that provides a durable water-repelling surface on glass. WaterOFF! treated glass repels rain, snow, and sleet for drastically improved visibility. The treated glass enables easy removal of ice, salt, mud, dirt and bugs. When used on automotive windshields, the product can minimize the use of wipers in heavy rain and high-speed driving conditions. The key differentiation between WaterOFF! and other surface coatings is that it is highly durable and can withstand abrasion, erosion, ultraviolet radiation, and chemicals for a much longer period of time. The product is equally applicable for both OEM and aftermarket.
Spray a thin layer of WaterOFF!TM solution onto the glass surface. Avoid pointing the spray nozzle to the face. Take a cotton cloth or towel to buff the wetted surface in a circular and overlapping motion to create an evenly hazy surface. Reapply WaterOFF! solution to ensure uniform and complete coverage. Allow the hazy surface to dry 5-10 minutes. Remove the haze with a dry cotton cloth or towel by forcefully wiping the surface until the surface is crystal clear. Avoid applying the treatment at temperatures below 10°C and directly under strong sunshine.
