Nycote 99 EcoShield
Nycote® 99 EcoShield is an advanced nylon-epoxy coating designed for high-performance protection in aerospace, electronics, medical, and industrial settings. Building on the trusted Nycote® 7-11 formula, EcoShield offers improved adhesion, extended shelf life, and a low-VOC, environmentally conscious composition. Its smooth, self-leveling finish forms a pinhole-free barrier that resists corrosion, friction, and chemical exposure—even in the most demanding environments. Tested to meet rigorous outgassing standards, Nycote® 99 EcoShield is ideal for applications where reliability is mission-critical.

A Legacy of Protection, Reinvented for the Environment
Nycote® 99 EcoShield is our formulation based off Nycote 7-11. 99 EcoShield 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

Storage Temperature Requirements
+- 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® 7-11 Dark Blue has a six-month shelf life. The container can be opened, applied and then re-sealed for a period of six 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
+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)
