OF-136-G2: Optical Fiber Primary Coating
OF-136-G2 is a new improved version of the original OF-136 optical fiber coating. The major improvements include better endurance under wet conditions (such as 85C hot water immersion) and better thermal stability. These improvements are expected to enable higher reliability and higher temperature operation, which can be beneficial for high-power fiber lasers.

OF-136 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 both light and moisture.
