OF-140-N3 is a low refractive index optical fiber coating, developed for the cladding of optical fibers. The material is designed to be used in Optical fiber Drawing Towers.
OF-140-N3 is a new version of OF-140-N. It has better adhesion and higher modulus. In addition, OF-140-N3 does not have the strong acidic odor of OF-140-N. It should provide a more comfortable working environment.

- Avoid unnecessary exposure to ambient light and moisture.
- Long-term storage should be at ambient conditions of 10-30ºC.
- The coating is supplied in glass bottles. Keep the container closed to avoid moisture penetration.
- The shelf life is 12 months.
OF-140-N3 is intended to be used in optical fiber drawing towers. UV curing is done under nitrogen. Typically, a dose of 1000-2000 mJ/cm2 is necessary. Any UV source in the range of 300-400 nm can be used. When properly cured under nitrogen, the surface should be non-tacky.
Keep the bottle closed at all times when not in use. The material is sensitive to light.
