RADIATION CURABLE RESIN COMPOSITION AND OPTICAL FIBER MADE BY USING THEREOF

摘要

PURPOSE: A photo-curable resin composition is provided to ensure a low shrinkage and expansion ratio after a period of high temperature and to minimize tensile strength, adhesive force, and the strip force rate of optical fibers. CONSTITUTION: A photo-curable resin composition comprises 40~80 weight% of photo-polymerizable urethane(meth)acrylate oligomer, 10~40 weight% of low viscosity multifunctional urethane acrylate oligomer, and 1~10 weight% photoinitiator. The low viscosity multifunctional urethane acrylate oligomer has a viscosity of 100,000 cps or less at 25°C in the addition to 1~20 parts by weight of acryl monomer.
