The weathering of UV cured films containing two kinds of acrylated urethane oligomers, and the influence of different additives (HALS, UVA and TiO2), was investigated by various methods such as colorimeter, glossmeter, microhardness tester, FT-IR and AFM. The UV cured film containing the acrylated aromatic urethane oligomer showed worse photodegradation than that containing the acrylated aliphatic urethane oligomer. In the case of the UV cured films containing the acrylated aromatic urethane oligomer, those stabilized using both HALS and UVA showed the highest photostability. |
