UV5126 will cure under sufficient UV 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
Tack free time (1mm) 5 – 10S
Deep curing time (1mm) 15 – 20S
Full cure energy (1mm) 600 mj/cm²


The following data are measured after curing with a high-pressure mercury lamp source with a cumulative energy of 600mj/cm²
