- Product Highlights
NANOMYTE® SR-100EC is a transparent, micron-thick coating that provides both scratch resistance and easy-to-clean properties to surfaces. The waterborne SR-100EC coating can be applied to plastics such as polycarbonate, PMMA, PET, polyurethane, epoxy, as well as metals such as stainless steel, aluminum, titanium, brass and chrome. The surface treatment is mechanically stable, is highly repellent to water and oils, and it enhances lubricity. By applying SR-100EC on the surface of components, soil and liquids simply slide off the surface, thereby helping prevent deposits and extending the time between cleanings.
NEI’s SR-100EC coating is based on a patent pending, water-based coating composition comprised of functionalized perfluoropolyethers (PFPEs). Although PFPEs are known for their non-stick and lubricating properties, it has been a major technical challenge to incorporate them into a stable formulation that can lead to a coating with sufficient adhesion to various substrates.
NEI’s SR-100EC formulation overcomes this stability issue. Additionally, while PFPE-based, easy-to-clean coatings currently on the market generally form very thin (< 100nm) coatings, SR-100EC coatings have a thickness of 2-5 microns, thereby creating a more mechanically stable coating that cannot easily be removed by abrasion, harsh cleaners or chemicals.
SR-100EC is easy to use and is ideally suited for optical lenses, touch screen protectors, stainless steel appliances, hand rails, and faucets. The liquid coating solution can be applied by dipping, spraying, roll or flow coating and is available in 1, 5, and 55 gallon quantities.

- 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, Part B, and Part C by weight using the following ratio: 5 to 3 to 2 (A:B:C). 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.- Clean Up
Clean tools and flush equipment thoroughly with acetone before product dries. Once coating is dry, the tools will not clean with acetone or any other solvent.

- 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-100EC.- Curing Conditions
NANOMYTE® SR-100EC is thermally cured at an elevated temperature. Recommended curing conditions:
- PMMA: 4 hours at 85°C
- Polycarbonate: 1 hour at 120°C
- Other: 30 minutes at 150°C (for substrates that can withstand high temperatures)
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.

Storage & Handling
- Storage and Handling
Precautions for Safe Handling
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.
Conditions for Safe Storage
For best coating performance, store Part C in a freezer or a refrigerator. Keep the containers of Part A and Part B tightly sealed and store in a cool and dry place. Avoid storage above 30 °C / 86 °F and contamination with incompatible materials. Keep away from heat, sparks, flames and other sources of ignition. Residual vapors might explode on ignition.
