NANOMYTE® SAF-100 coated polycarbonate resists fogging over hot water (left) and upon being removed from a freezer (right).

NANOMYTE® SAF-100 is an optical grade, anti-fog coating with excellent abrasion and water resistance. The coating passes EN 168 (Personal eye-protection. Non-optical test methods) for Mist Retardant Anti-fog Coatings and also exhibits anti-frost properties. The novel coating technology is based on NEI’s patented scratch-resistant transparent coating, commercially known as NANOMYTE® SR-100. The scratch resistant base coating formulation has been modified with unique amphiphilic compounds which are locked into the coating matrix, thereby leading to durable anti-fog performance. The scratch-resistant coating matrix provides a high degree of mechanical durability, with a pencil hardness of HB. As a result, the anti-fog properties are retained after repeated washing with soap and water.

NANOMYTE® 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.

Features & Benefits:

  • Exceptional Anti-fog Performance – Resists fogging in aggressive conditions
  • Outstanding Durability – Maintains mechanical integrity under water, ideal for permanent application
  • Excellent Abrasion and Mar Resistance – Improves the scratch and mar resistance of coated plastic substrates
  • Thin and Highly Transparent – Greatly minimizes optical distortion
  • Easy Application Can be applied by spraying, dipping, or flowing

Technical Data Sheet
The liquid coating solution is available in liter and gallon quantities and can be applied by dipping, spraying, roll or flow coating. NEI also offers in-house coating services for customer’s parts, as well as coating development services, wherein coating formulations are customized to address specific customer requirements.

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.
