EFIRON  Primary & Secondary
coating series is radiation-curable (UV) acrylate useful
for optical fiber coating process. EFiRON Primary & Secondary
coating series has suitable glass transition temperature,
rapid cure property, non-yellowing, thermal resistance,
high oxidative and hydrolytic (moisture) stability which
are required by optical fiber industry application. EFiRON Primary & Secondary coating series can be easily
removed from the clad without damage to the optical fibers
for splicing and connection procedure. |
