RADIATION CURABLE COATING

摘要

A radiation curable coating for optical fiber, comprising: 20-70 wt% of epoxy polyurethane (methyl) acrylates oligomer, 20-70 wt% of active monomer diluent, 1-10 wt% of photoinitiator and 1-10 wt% of auxiliary; the epoxy polyurethane (methyl) acrylates is obtained via a chemical reaction between the polyurethane (methyl) acrylates and the epoxy (methyl) acrylates, and has better uniformity and stability.
