- Coating Application
It is recommended that coating application be performed in a clean environment to minimize surface defects. To make the coating solution, combine Part A and Part B at 9/1 weight ratio and mix well by stirring briefly. The coating may be applied by spraying, dipping, flowing, brushing or rolling. For spraying, 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 induction time for spray application is 30 min, i.e., wait at least 30 minutes after mixing before coating application. For other application methods, it is recommended to age the mixed solution for at least 16 hours to obtain a highly transparent coating.
For Best Performance : Although the mixed coating solution is stable indefinitely, it is recommended to use the solution within 72 hours after mixing for best results.- Clean Up
Clean tools and flush equipment thoroughly with water followed by isopropyl alcohol or acetone before product dries. Once coating is dry, the tools will not clean with acetone or any other solvent.

Technical Details & Test Data
- Surface Preparation
Ensure surfaces to be coated are clean and dry and apply a primer if necessary. NEI supplies two primers for polymer substrates: SRP-50 for PMMA and SRP-51 for PC. The primer may be applied by dipping, flowing, spinning, rolling or spraying.
For spraying, 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. A single pass of spraying is recommended for the primer. The primed parts should be dried at 80ºC for 10 min before application of NANOMYTE® SR-100.- Chemical Resistance
Passes MIL - PRF - 32432 standard - no visual damage after 24 hours of exposure to the following chemicals :
- Bleach (6.0 wt% sodium hypochlorite)
- 30% concentration DEET
- Fire resistant hydraulic fluid (MIL - PRF - 46170)
- Hydraulic fluid
- Gasoline (87% Octane)
- Motor oil
- JP8 fuel (MIL - DTL - 83133E)
- Curing Conditions
- NANOMYTE® SR-100 is thermally cured at an elevated temperature. Recommended curing conditions:
- PMMA: 2 hours at 80°C
- Polycarbonate, ABS, PC-ABS: 1 hour at 100 – 120°C (depending on heat distortion temperature)
- 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, keep container tightly sealed and store in a dry and cool area. Avoid storage above 40°C / 104°F and contamination with incompatible materials. Keep away from heat, sparks, flames and other sources of ignition. Residual vapors might explode on ignition.
