NANOMYTE® SR-200EC
NANOMYTE® SR-200EC is a transparent, highly hydrophobic, two-part liquid coating that results in relatively thin coatings with an easy-to-clean functionality. The thermally cured coating is mechanically robust, highly repellent to water and oils, and enhances lubricity, however the key aspect is that the coating is free of fluorinated materials and environmentally sustainable.

- HIGHLIGHTS
SR-200EC provides both scratch resistance and easy-to-clean properties to a variety of surfaces. It can be applied on plastics (such as polycarbonate, PMMA, PET, polyurethane, & epoxy) as well as metals (such as stainless steel, aluminum, titanium, brass and chrome). While it is recommended to be applied to a thickness of a few microns, it can also be applied thinner – much less than one micron.
- Abrasion Resistance
* Taber abrasion test, polycarbonate substrate, CS - 10F wheels, 500g load, 500 cycles
- Coating Application
It is recommended that coating application be performed in a clean environment to minimize surface defects. To make the coating solution, use a dust-free container and combine Part A and Part B at a 3:1 ratio by weight. Mix well by stirring briefly (avoid vigorous stirring to minimize foam formation). Wait at least two hours before coating application. The coating may be applied 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.
- Surface Preparation
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® SR-200EC.
