Nycote 99 EcoShield is our newest formulation based off Nycote 7-11. 99EcoShield is a highly crosslinked multipolymer nylon epoxy coating. Trusted since the 1960’s by all major OEM’s to provide an excellent permanent barrier from harsh environments. The Nycote formulation is chosen over other coating technologies because of its unique ability to cure pinhole-free and self-level. The process allows for complete encapsulation of the part and will protect for years due to the strength of the epoxy and flexibility of the nylon polymer.

Nycote 99 meets the standards for outgassing per ECSS-Q-ST-70-02

  • Store at 70°F (21°C). Keep away from fire or flame.
  • Note: Ideal storage temperature is 70°F (21°C); acceptable storage range is between 65°F to 80°F (18.3°C to 26.7°C). Storing below 65°F (18.3°C) may cause cloudiness or gel; heat at 180°F (82°C) for two hours. This should restore the product to its normal liquid condition. If possible, re-verify viscosity with Zahn #2 cup (50-90 seconds).
  • Nycote® 99 has an eight-month shelf life. The container can be opened, applied and then re-sealed for a period of eight months. The storage temperature should be maintained for the entire shelf life period. The container must always be stored in an upright position. If the storage temperature is not the ideal, nor within the acceptable range, the result may change the nature of the Nycote® product, as well as, causing cloudiness of the liquid. At all times, the product should be kept from freezing.


  • Allow one to two hours to become tack free. In dry air allow 72 hours at room temperature for full cure or:
  • Heat 12 hours @ 120°F (49°C)
  • Heat eight hours @ 150°F (66°C)
  • Heat four hours @ 180°F (82°C)
  • Heat two hours @ 220°F (105°C)
  • Cure film temperature range is -70°F to +400°F (-57°C to 204°C)

Nycote Laboratories Corporation manufactures anti-corrosive coatings with a variety of tinting options.
