UV5129 will cure under sufficient ultraviolet irradiation conditions. The curing speed and depth depend on the light intensity, spectral distribution of the light source, irradiation time and the light transmittance of the adhered material. The following data are measured under the condition of ultraviolet radiation of 20mw/cm2 produced by a high-pressure mercury lamp:

Properties Reference
Fixed time (S) 4 – 6s
Tack free time (1mm) 10 – 15s
Deep curing time (1mm) 25 – 30s
Full cure energy (1mm) 800 mj/cm²


The following data are measured after curing with a high-pressure mercury lamp source with a cumulative energy of 800mj/cm²

Properties Test method Reference
