Easy to Apply

NANOMYTE^® SAF-100 is an anti-fog coating for permanent application. The product is sold as a two-part liquid coating composition. It can be applied using standard coating processes, such as spraying, dipping, or flow coating and is thermally cured. 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.

SAF-100 is ideally suited for surfaces where prevention of fogging and frosting is needed. The coating may be used on sports and safety goggles, glasses, face shields, respirators, outdoor signage, camera heads, environmental enclosures, windows, mirrors, windshields, displays, and other applications where fogging needs to be mitigated.

SURFACE PREPARATION
Ensure surfaces to be coated are clean and dry and apply a primer if necessary (such as polymer substrates). 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. A single pass of spraying is recommended for the primer. The primed parts should then be dried at 70 ºC for 10 min before application of NANOMYTE^® SAF-100.

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 a 10:1 weight ratio and mix well by stirring briefly. The coating may be applied by spraying, dipping, or flowing.

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 at approximately 25 to 30 psi. The induction time for spray application is 1 hour (i.e., wait at least 1 hour after mixing before coating application). For other application methods, it is recommended to age the mixed solution for at least 12 hours to obtain a highly uniform coating.

Although the mixed coating solution is stable indefinitely, it is recommended to use the solution within 72 hours after mixing for the best performance.

CURING
NANOMYTE^® SAF-100 is thermally cured at an elevated temperature. Recommended curing conditions:

• PMMA: 2 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.

Product Safety Information

Precautions for Safe Handling
Appropriate personal protective equipment should be used at all times. Provide good ventilation or extraction. Avoid contact with eyes, skin, and clothing. Avoid prolonged or repeated breathing of vapor. Wash hands thoroughly after handling. Keep away from heat, sparks, flames and other sources of ignition.

Conditions for Safe Storage
For best coating performance, keep containers 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.
