Nycote 99

nycote-99

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

APPLICATION INSTRUCTIONS

STORAGE TEMPERATURE
REQUIREMENTS

VIEW MORE
  • 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.

CURE TIME TABLE

VIEW MORE
  • Allow one to two hours to become tack free. In dry air allow 72 hours at room temperature for full cure or:
  • Heat twelve 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)

* Always check with your own internal engineering department to ensure materials you intend to force cure can withstand the temperatures listed on the Nycote table.
