OF-145-N: Optical Fiber Coating
OF-145-N is a low refractive index optical fiber coating, developed for the cladding of optical fibers. The material is designed to be compatible with Optical fiber Drawing Towers.
The extension N denotes there is No adhesion promoter in the formulation. This allows a longer shelf life, but adhesion under wet conditions is lower.

The product is supplied pre-filtered to below 1 micron particles.
- 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 container closed to avoid moisture penetration.
- The shelf life is 12 months.
OF-145-N is intended to be used in optical fiber drawing towers. The UV curing is done under nitrogen. Typically, a dose of 1000-2000 mJ/cm2 is necessary. Any UV source in the range 300-400 nm can be used. When properly cured under nitrogen, the surface should be non-tacky.
Keep the bottle closed in all times when not in use. The material is sensitive to light.
