“…On the other hand, the application of other methods, such as the direct pull-of or a torque spanner [8] is very difficult in the case of UV-curable polymers because they require a free access of UV radiation to the liquid composition placed between two solid specimens. In a previous paper [9] we have described a method for determination of adhesion of the UV-curable polymer coatings surrounding the cylindrical objects. This method consists in tearing off the thin cured polymer ring from the fused silica rod using the tensile tester, assuming that the polymer adhesion to the rod surface is equal to the highest strain force reg-istered by the tester.…”

Measurements have been made of the adhesion of liquid and UV-cured epoxyacrylates to a fused silica surface. The fused silica surface was dehydroxylated in the 200-900°C temperature range. Also, the contact angles of water, diiodomethane and formamide on the fused silica surface were measured. Using the contact angle results, the 'harmonic mean' method and the acid-base interactions approach, the dispersion (Lifshitz-van der Waals) and electron donor and electron acceptor components of the fused silica surface as well as epoxyacrylate polymer surface free energy were calculated. It was found that, probably because of the physically adsorbed water, the hydroxylated surface of the fused silica is basic and that the adhesion of the epoxyacrylate polymer to this surface depends on its basicity.

SYNOPSIST h e dependence of adhesion of four various UV-curable protective coatings of optical fibers t o the surface of fused silica on the time of UV irradiation was investigated. T h e maxima of adhesion were observed in short periods of time of curing. Comparison of adhesion values t o the hardness, gel content, and contact angles of water measured on the polymer surface revealed that adhesion of epoxyacrylate protective coatings of optical fibers depended on the inner structure of the polymer rather than on its surface properties. This observation was confirmed by IR studies.

Ultraviolet (UV)-curing behavior of an epoxy acrylate resin system comprising an epoxy acrylate oligomer, a reactive diluent, and a photoinitiator was investigated by Fourier transform infrared (FTIR) spectroscopy. The conversion changes of the resin system containing 20 phr of 1,6-hexanediol diacrylate as a reactive diluent and 2-hydroxy-2-methyl-1-phenyl-propan-1-one as a photoinitiator were measured under different UV-curing conditions. The fractional conversion was calculated from the area of the absorption peak for the vinyl group vibration occurring at 810 cm Ϫ1 . The effects of photoinitiator concentration, total UV dosage, one-step or stepwise UV irradiation, UV intensity, atmosphere, and temperature on the curing behavior of the resin system were investigated. The conversion of the resin system increased rapidly at the initial stage of the UV-curing process but increased very slowly after that. The final conversion of the resin system was mainly affected by total UV dosage.
