UV5137 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
Surface drying time (1mm) 15-20S
Deep curing time (1mm) 45-50S
Full cure energy (1mm) 1200 mj/cm²
