THE PROPERTIES OF POLYMER PROTECTIVE COATINGS OF OPTICAL FIBERS .2. THE INFLUENCE OF CURING TIME ON ADHESION OF UV-CURABLE COATINGS TO FUSED-SILICA SURFACE

The dependence of adhesion of four various UV-curable protective coati ngs of optical fibers to the surface of fused silica on the time of UV irradiation was investigated. The maxima of adhesion were observed in short periods of time of curing. Comparison of adhesion values to the hardness, gel content, and contact angles of water measured on the po lymer surface revealed that adhesion of epoxyacrylate protective coati ngs of optical fibers depended on the inner structure of the polymer r ather than on its surface properties. This observation was confirmed b y IR studies. (C) 1995 John Wiley and Sons, Inc.
